The Floating Nomad: Indigo Geodes in a Glass-Floor Atrium

Suspended between the azure horizon and the crystalline depths of the ocean below, the atrium breathes. Here, the boundary between interior sanctuary and the raw, untamed cliffside dissolves, anchored only by the presence of our defining centerpiece: the indigo-dyed anti-gravity rug. Its weave is a masterclass in haptic-gravitational engineering, where micro-myco fibers—grown into complex, repeating geometric lattices—defy the standard pull of the earth. The rug does not simply lie upon the glass; it hovers, a shimmering, weightless stratum of midnight-blue geodes and cerulean veins that seem to pulsate in sync with the rhythmic tide below.

Natural sunlight, filtered through the salt-misted air, strikes the rug’s crystalline geometry, fracturing light into a soft, bioluminescent blue halo that climbs the walls. This ethereal glow softens the sharp, architectural lines of the glass floor, creating a sense of profound suspension. The indigo tones, ranging from deep, bruised violet to the palest oceanic wash, harmonize with the sheer white linen draperies that dance in the cross-breeze, their movement echoing the fluid, weightless nature of the textiles beneath them.

Curated Furniture Dynamics

To anchor a space that literally defies gravity, the furniture selection requires a dialogue of weighted elegance and organic warmth. Mid-century modern teak pieces, characterized by their tapered, needle-like legs, appear as if they are poised to take flight. The wood’s deep, honeyed grain serves as a grounding counterpoint to the synthetic, crystalline brilliance of the rug.

• Teak Elements: Low-slung lounge chairs with woven rattan backrests provide a tactile, bohemian contrast to the rug’s high-tech, futuristic fiber construction.
• Travertine Accents: A raw, honed travertine block coffee table serves as a solid, geological anchor, its pitted, sandy surface highlighting the rug’s lustrous, polished depth.
• Brushed Bronze Details: Slim, brushed bronze floor lamps or side table legs introduce a metallic warmth that pulls the gold-flecked crystalline patterns out of the weave and into the surrounding air.
• Textile Pairing: Throw pillows crafted from raw, heavy-weight silk in shades of burnt terracotta or desert sand create a daring, vibrant contrast against the cool indigo landscape of the floor.

Color Palette and Atmospheric Control

The space thrives on a high-contrast dialogue between the cavernous depth of the indigo fibers and the transparency of the surrounding atrium. The goal is to avoid the clinical feel of a glass enclosure, inviting instead the warmth of a nomadic retreat. By pairing the deep blue of the anti-gravity bohemian rugs with the amber undertones of aged teak and the cool, chalky finish of plaster-white walls, the atrium transforms into a sanctuary that feels both ancient in its nomadic soul and futuristic in its execution.

Weightless Earth: Ochre Myco-Weaves in a Brutalist Loft

Dust motes dance within the sharp, clinical shafts of overhead spotlights, illuminating a space where architecture meets the ethereal. Here, within the uncompromising envelope of raw, poured concrete and exposed rebar, the environment demands a soul—a counterbalance to the frigid structural integrity of the loft. The floor plane is redefined not by its cold, gray expanse, but by a sudden, suspended presence: an ochre-toned myco-crystalline rug. It hovers, a gentle defiance of physics, its organic, mycelium-infused fibers pulsing with a warm, subterranean glow that pulls the eye downward to the heart of the room.

The texture of these anti-gravity Bohemian rugs is nothing short of transformative. By utilizing haptic-gravitational weave technology, the rug creates a subtle, rhythmic lift, allowing it to settle a fraction of an inch above the polished concrete surface. This slight levitation softens the acoustic profile of the loft, turning an echo-heavy chamber into a sanctuary of muffled silence and plush tactile indulgence. The ochre pigment—a complex blend of terracotta, burnt saffron, and dried earth—anchors the space while suggesting a nomadic history, grounding the brutalist backdrop with a sense of warm, ancient permanence.

Furniture placement here relies on a study of deliberate contrasts. To anchor the floating expanse, place a pair of low-slung, overstuffed cream bouclé armchairs at the periphery of the weave. Their nubby, cloud-like silhouette mirrors the organic irregularity of the rug’s edges. Position a massive, reclaimed travertine block table in the center, allowing its cool, porous stone to bridge the gap between the concrete floor and the weightless, fiber-based warmth of the rug. A blackened steel fireplace acts as the room’s visual anchor, providing a stark, vertical tension that makes the ochre glow of the flooring feel even more kinetic and alive.

Curated Design Elements for the Brutalist Loft

• Material Harmony: Pair the rug’s fungal-derived resilience with raw travertine, blackened brushed steel, and heavy-weight linen drapery in sand-dune tones.
• Lighting Strategy: Utilize dimmable, narrow-beam spotlights aimed at a forty-five-degree angle; this maximizes the haptic depth of the crystalline weave, casting long, dramatic shadows that make the rug appear to undulate.
• Accent Palette: Complement the ochre saturation with deep charcoal, oxidized bronze, and muted olive foliage—think large-leafed Ficus lyrata or sculptural cacti—to reinforce the earth-meets-modernity aesthetic.
• Spatial Flow: Leave a deliberate five-foot margin between the edge of the rug and the base of the concrete walls, allowing the “levitation gap” to remain visible as a continuous ribbon of light around the room’s perimeter.

The alchemy of this design lies in the juxtaposition of the permanent and the kinetic. While the concrete structure speaks of cold, fixed duration, the ochre myco-weave introduces a living, breathing fluidity. It is a space designed for deep contemplation, where the weight of the world is literally stripped away at the doorstep, replaced by the soft, buoyant luxury of a floor that refuses to be held down. Every step across the surface feels dampened and hushed, a dreamlike interaction between human weight and the intelligent, supportive fibers of the weave.

Haptic-Gravitational Sanctuary: Silver-Mist Boho in a Zen Meditation Chamber

Morning light does not merely enter this circular chamber; it performs a soft, rhythmic dance against the curvature of the glass, pooling across the floor like liquid dawn. At the heart of this sanctuary lies the silver-mist haptic-gravitational rug, an architectural marvel of 2026 design that defies the static nature of traditional textiles. Its surface, engineered with myco-crystalline filaments, appears to suspend itself mere millimeters above the polished concrete, creating a gentle, rippling effect as if the air beneath it is catching a terrestrial breeze. The sheen of the silver mist catches the diffused light, casting elongated, ethereal shadows that blur the boundary between the room’s foundation and the space beyond the glass walls.

The Bohemian soul of the piece is anchored by its raw, organic movement, yet it commands a level of sophistication required for a high-concept meditation suite. To ground the levity of the anti-gravity weave, we introduce low-profile floor cushions upholstered in heavy, matte-finish charcoal silk. The contrast is profound: the rug provides a shimmering, kinetic energy, while the silk anchors the occupant with a grounded, silent weight. A minimalist incense holder, carved from brushed, cool-toned stone, rests off-center, acting as a static anchor point that draws the eye toward the center of the rug’s gravitational vortex.

Refining the Sensory Palette

• Textural Anchors: Pair the silver-mist rug with raw, unpolished basalt or volcanic stone accents to emphasize the tension between “float” and “earth.”
• Chromatic Harmony: Incorporate deep slate blues, whisper-thin dove greys, and charcoal to maintain a monochromatic, meditative intensity that allows the rug’s luminescence to take center stage.
• Lighting Dynamics: Utilize low-lumen, recessed perimeter lighting to accentuate the rug’s rippling edge, making the material appear to pulse slowly in time with the user’s breath.

The layout of this chamber demands an absence of clutter, allowing the anti-gravity bohemian rug to function as the primary kinetic element of the architecture. Avoid overhead lighting entirely; instead, rely on the play of the sun as it tracks across the sky, shifting the rug’s silver highlights from pearlescent morning whites to moody, metallic violets as dusk approaches. The furniture choices must remain subservient to the rug’s reach—think singular, monolithic seating pieces or reclaimed travertine blocks that offer a rugged, porous texture against the smooth, synthetic precision of the myco-weaves. This is a space for the tactile and the transcendental, where the act of sitting becomes an exercise in suspended stillness.

By integrating these floating textile forms into the Zen aesthetic, the room moves away from traditional austerity and toward a living, breathing environment. Every ripple in the crystalline fiber reacts to the weight of the cushions and the movement of the occupant, creating a bespoke landscape that changes perpetually. The result is a sanctuary that feels less like an interior and more like a meditative cloud, perfectly contained within the circular glass confines of the home.

Suspended Sunset: Coral-Infused Textures in a Moroccan Sunken Lounge

Dust motes dance within the amber glow of a Moroccan sunken lounge, where the boundary between architecture and atmosphere dissolves entirely. At the heart of this sanctuary lies a centerpiece that defies the laws of traditional textile design: the Anti-Gravity Bohemian rug. Here, the floor does not merely support the space; it elevates it. The fibers, infused with crystalline myco-structures, lift mere millimeters above the intricately tiled floor, creating a literal suspension that transforms the act of stepping onto the rug into a rhythmic, buoyant experience. The vibrant coral hues of the weave pulse softly, catching the golden light filtered through ornate brass lanterns and casting prismatic reflections onto the surrounding plaster walls.

This is a masterclass in controlled opulence. The sunken architecture creates an intimate, cocoon-like feeling, perfectly balanced by the weightless nature of the floor covering. By choosing a rug that hums with kinetic energy, the room sheds the heaviness often associated with traditional Moroccan motifs, replacing it with a fluid, dreamlike presence. The burnt orange silk-upholstered low sofas frame the lounge with a sophisticated, monochromatic intensity, anchoring the brilliance of the coral rug without tethering it to the ground. The play of light between the intricate, shadow-casting brass work and the luminous, glowing fibers of the rug creates a sensory layering that feels both ancient and profoundly futuristic.

Curated Design Palette and Furniture Harmony

To cultivate a space where the Anti-Gravity Bohemian rug functions as the primary visual anchor, select furniture that complements the haptic-gravitational movement of the floor rather than competing with it. The objective is to maintain a low-profile silhouette that draws the eye toward the floor’s ethereal glow.

• Primary Furniture: Low-slung, modular sofas upholstered in raw, unbleached silk or matte burnt-orange linen to ensure the coral hues of the rug remain the focal point.
• Accent Tables: Reclaimed travertine block tables, chosen for their porous, earth-bound texture which contrasts beautifully with the synthetic, levitating nature of the rug fibers.
• Lighting: Hand-hammered brass lanterns suspended at staggered heights to cast oscillating, geometric shadows that mirror the crystalline patterns within the rug.
• Supporting Accents: Brushed bronze floor vessels filled with dried pampas or structural desert flora to bridge the gap between the room’s metallic architectural elements and the organic vibrancy of the coral weave.

The success of this lounge lies in its mastery of temperature. While the lighting is intentionally warm—verging on the amber spectrum—the anti-gravity properties of the rug introduce a cool, stabilizing breath of air. This prevents the room from feeling oppressive despite the density of the decorative tile work. When the sun dips low, the interaction between the brass lantern flickers and the crystalline coral fibers creates a shimmering, liquid effect on the floor, suggesting that the entire lounge is floating above the desert floor itself. It is a space designed for slow evenings, where the furniture invites reclining, and the floor invites a sense of perpetual, effortless drift.

Ethereal Botanicals: Emerald Myco-Crystals in a Biophilic Greenhouse Study

The boundary between the organic wild and the curated interior dissolves the moment you step onto the shimmering, levitating plane of the Emerald Myco-Crystalline weave. Nestled within a soaring greenhouse study where the air tastes of damp earth and verdant chlorophyll, this rug serves as the room’s gravitational anchor—or rather, its deliberate defiance of it. As sunlight filters through the dense canopy of fiddle leaf figs and cascading ivy, it fractures against the rug’s crystalline fibers, casting liquid, emerald-hued light across the walls. The rug hovers a precise three inches above the stone flooring, creating a haptic-gravitational field that transforms every footstep into a soft, cushioned glide. It is not merely a floor covering; it is a suspended garden floor that breathes in tandem with the surrounding flora.

The architecture of the space relies on the contrast between raw, weathered textures and the refined, semi-translucent quality of the weave. Positioned at the heart of the room is a reclaimed driftwood desk, its gnarled, salt-worn timber providing a grounding, jagged silhouette against the rug’s polished, bio-luminescent surface. Beside it, a glass-topped writing table seems to vanish into the emerald haze, allowing the focus to remain entirely on the juxtaposition of the living plants and the synthetic-organic material of the rug. The Anti-Gravity Bohemian Rugs featured here possess a depth that mimics the forest floor, yet they offer a clean, clinical perfection that prevents the room from feeling unkempt.

Refined Material Palette and Furniture Pairings

Designing around this emerald centerpiece requires a commitment to a palette that respects the raw intensity of the crystals while embracing the calming influence of the greenhouse. Warm, earthy neutrals and metallic accents prevent the green from feeling overwhelming, ensuring the space remains a sanctuary for deep work and meditative contemplation.

• Seating: Pair the emerald weave with low-slung armchairs upholstered in heavy, nubby bouclé in a warm, plaster-white tone to mirror the look of limestone.
• Tables: Integrate brutalist, reclaimed travertine block tables to echo the rough-hewn texture of the driftwood desk.
• Lighting: Utilize brushed bronze floor lamps with amber-tinted bulbs, which amplify the glow of the myco-crystals during the twilight hours when the greenhouse dims.
• Accents: Introduce oversized terra-cotta planters and matte black ceramic vessels to provide a sharp, grounding contrast to the light-refracting properties of the floor.

When the afternoon sun hits the canopy, the dappled light dancing across the emerald rug creates a kinetic art installation that changes with every passing cloud. The haptic feedback is subtle, offering a responsive buoyancy that makes standing at the drafting table feel effortless, even during long, grueling hours of creative work. It is the ultimate expression of Biophilic luxury—where the floor itself mimics the vitality of the ecosystem above, ensuring that the inhabitant is always in harmony with the rhythm of the living world. The result is a space that feels both ancient in its botanical abundance and futuristic in its weightless, crystalline sophistication.

Lunar Bohemian: Iridescent White Weaves in a Minimalist Cloud-Bedroom

There is a profound stillness that descends when architecture ceases to be heavy. In this sanctuary, the boundaries between floor and atmosphere dissolve, surrendered to the ethereal presence of the Anti-Gravity Bohemian Rug. Suspended mere millimeters above the high-gloss white concrete, the rug glows with a pearlescent, lunar luminescence, acting as the radiant heart of a space designed to defy the very concept of weight.

The room is a symphony of monochromatic light. Walls are swathed in heavy, floor-to-ceiling white silk drapes, their organic folds catching the soft, hidden cove lighting that bleeds from the ceiling perimeter. The rug itself—a masterpiece of Myco-Crystalline engineering—shimmers with an iridescent quality that mirrors the shifting intensity of dawn and dusk. As the haptic fibers respond to the gravity-neutral field, they create a subtle, rippling motion underfoot, a tactile invitation to shed the burdens of the external world.

The furniture layout prioritizes horizontal planes, emphasizing the floating aesthetic. A low-slung platform bed, upholstered in cream-toned crushed velvet, appears to hover within the center of the space. Beside it, the room is anchored not by wood, but by transparency and soft texture. The pairing of the rug’s crystalline, weightless weave with the plush, grounding weight of the velvet bed creates a sophisticated tension—the ultimate dialogue between the terrestrial and the celestial.

Curated Spatial Elements

• Reflective Foundation: The high-gloss floors act as a secondary horizon, doubling the visual impact of the rug’s iridescent sheen and amplifying the feeling of an infinite, cloud-bound expanse.
• Structural Counterpoints: Integrate brutalist-inspired, curved plaster side tables to provide a matte, architectural contrast to the shimmering, kinetic energy of the rug.
• Ambient Illumination: Opt for recessed, warm-spectrum LEDs that graze the wall-to-wall silk, ensuring the room’s light source remains unseen, keeping the focus entirely on the rug’s hypnotic, floating glow.
• Texture Layering: Combine the crystalline, slightly cooling touch of the anti-gravity fibers with warm, heavy-knit mohair throws draped casually across the velvet bed frame.

Choosing an Anti-Gravity Bohemian Rug for this bedroom is a move toward sensory liberation. The color palette—strictly whites, bleached ivories, and subtle silver-mist undertones—ensures that the focus remains on the play of light. When the evening light hits the crystalline weave, the rug releases a soft, prismatic dispersion, casting faint halos of pearl and lavender onto the surrounding silk walls. This is not merely a design choice; it is an environment engineered for deep, restorative repose, where the physical sensation of stepping onto a cloud is finally realized in an interior landscape.

The lack of traditional furniture legs in this room—opting instead for floating platforms and recessed storage—ensures that the sightline is never broken. The eye travels uninterrupted from the reflective floor, across the iridescent crests of the rug, to the soft, enveloping velvet of the bed. It is a masterclass in minimalist weightlessness, a space that breathes, shifts, and eventually, elevates the occupant.

Amber Resonance: Warm Tones in a Floating Mid-Century Library

The air in this circular sanctuary feels different—charged with the quiet hum of a thousand leather-bound volumes and the static-free silence of a levitating floor. At the heart of this mid-century library, the Amber-toned anti-gravity rug does more than occupy space; it anchors the room in a state of perpetual, graceful suspension. As the Myco-Crystalline fibers hover precisely two inches above the dark, herringbone-patterned walnut flooring, they catch the afternoon light, casting a liquid, golden radiance that washes over the lower reaches of the bookshelves. The rug functions as a luminous foundation, its weightless composition turning the act of reading into an experience of gentle, atmospheric buoyancy.

The architecture of the room demands a dialogue between the organic warmth of the wood and the technical precision of the weave. By positioning a low-slung, Eames-inspired lounge chair in supple, cognac-colored leather directly atop the amber expanse, the silhouette of the room finds its perfect equilibrium. The chair’s molded plywood shell echoes the vertical rhythms of the walnut shelves, while the brass floor lamp beside it serves as a sharp, metallic counterpoint to the soft, shifting glow of the crystalline fibers beneath. The rug’s haptic-gravitational field ensures that every step taken toward the shelves feels cushioned and rhythmic, eliminating the harsh impact of traditional flooring and replacing it with a subtle, responsive rebound that mimics the texture of sun-warmed desert sand.

Integrating these advanced textiles requires a disciplined approach to the surrounding environment to ensure the room remains grounded in mid-century sophistication rather than drifting toward sterile futurism. The interplay of light is paramount. As dusk settles, the anti-gravity bohemian rug emanates a soft, bioluminescent hum, turning the amber fibers into a pool of glowing embers that redefine the geometry of the library.

Curating the Atmospheric Palette

• Textural Anchors: Contrast the synthetic, ethereal weave with heavy, matte elements. Reclaimed travertine block side tables offer the necessary geological weight to ground the room’s high-tech lightness.
• Leather & Metal Pairing: Opt for full-grain, oil-tanned leathers in tobacco or burnt sienna to pull the amber hues upward. Brushed, non-lacquered brass hardware on cabinetry prevents the rug from feeling too isolated, drawing the metallic gold undertones of the crystals into the rest of the decor.
• Lighting Dynamics: Incorporate dimmable, hidden LED strips behind the lowest walnut shelving tiers to spill light directly onto the crystalline edge of the rug, amplifying the “floating” visual effect during evening hours.
• Palette Cohesion: Pair the amber tones with deep forest green velvet drapery or accents of charcoal wool to prevent the room from becoming overly monochromatic, ensuring the warm, vibrating orange-golds remain the room’s primary focal point.

Within this circular geometry, the rug acts as a meditative platform. The way the fibers adjust to the user’s presence—subtly shifting their crystalline density—means that lounging with a rare first edition feels like floating on an intelligent, living fabric. It is a space where the weight of history, held in the books surrounding the perimeter, meets the absolute lightness of modern material science, creating a haven that feels simultaneously timeless and light-years ahead of its time.

Prismatic Drift: Multi-Dimensional Haptic Fibers in an Art Deco Creative Suite

Sunlight spills through the high-arched steel casements of the suite, fracturing into a thousand brilliant shards against the geometric ceiling motifs. Within this Art Deco sanctuary, the floor is no longer a static surface but a medium for movement. The installation of Anti-Gravity Bohemian Rugs anchors the expansive floor plan, their fibers engineered with a proprietary myco-crystalline density that grants the textile a subtle, rhythmic buoyancy. As one traverses the room, the rug’s surface responds to the weight of a footfall with a haptic shimmer, rippling like a pool of oil-slicked silk that shifts from deep violet to electrified copper, perfectly mirroring the bold, stepped architecture of the surrounding creative space.

The rug serves as the chromatic heartbeat of the room, grounding the high-drama emerald velvet sofas that curve elegantly along the perimeter. These sofas, upholstered in a lush, high-nap mohair, offer a soft, tactile contrast to the crystalline energy beneath. To enhance the Art Deco narrative, a series of gold-leaf nesting tables featuring sharp, angular silhouettes are placed deliberately atop the rug’s most iridescent patches. The metallic sheen of the gold catches the reflected prismatic light from the rug, creating a dialogue between the artisanal past and the gravity-defying future of textile design.

Curated Elements for the Prismatic Suite

• Seating Dynamics: Pair the rug with oversized, circular velvet ottomans in deep emerald or moss to emphasize the soft, organic flow of the Bohemian aesthetic against the rigid, linear ceiling geometry.
• Lighting Strategy: Utilize floor-to-ceiling brass arc lamps to cast a warm, concentrated glow across the crystalline fibers, which intensifies the iridescence of the weave during the golden hour.
• Material Accents: Integrate Nero Marquina marble side tables to provide a stark, obsidian backdrop that allows the shifting colors of the rug to truly pop.
• Spatial Layout: Anchor the rug centrally within the room’s primary geometric vertex, leaving a generous margin of polished herringbone parquet flooring to frame the “floating” effect of the piece.

The atmosphere is one of deliberate decadence. Because these Anti-Gravity Bohemian Rugs possess a weightless quality, they seem to hover slightly above the floorboards, casting a soft shadow that dissolves the boundary between the furniture and the architecture. This is a space designed for the creative mind—a place where the rigid symmetry of 1920s design language meets the fluid, impossible textures of the 2026 interior movement. Every element in the suite, from the faceted crystal chandeliers to the deliberate placement of the haptic textiles, works to disorient the senses in the most sophisticated way possible. The room feels less like a static interior and more like a captured moment of light-bending motion, perfect for an environment that demands both focus and profound aesthetic inspiration.

Celestial Softness: Pale Azure Gradients in a Waterfront Wellness Retreat

The boundary between the Mediterranean horizon and the interior sanctuary dissolves where the sea meets the sky, mirrored perfectly by the expansive, shifting hues of the Myco-Crystalline Haptic-Gravitational Weave. As natural light pours through floor-to-ceiling glass, the rug does not merely rest upon the sand-colored micro-cement floor; it hovers, a gentle, ethereal suspension that defies traditional anchoring. The pale azure gradient—moving from a translucent, misty white at the perimeter to a deep, oceanic cerulean at the core—mimics the tidal pull, creating a sensory dialogue with the waves just beyond the terrace.

In this wellness retreat, the weightless nature of the anti-gravity bohemian rugs becomes the anchor for a serene, monastic luxury. The texture is neither static nor purely fibrous; the haptic-gravitational filaments respond to the atmospheric pressure of the room, shifting in density to provide a cloud-like resistance beneath the feet. This is the zenith of 2026 interior curation: a space that feels less like a built environment and more like a captured moment of atmospheric drift.

To complement the fluidity of the azure gradients, the furniture is kept strictly organic and low-profile. A set of bleached white rattan armchairs, curved to mimic the organic geometry of shells, sits atop the rug’s lighter edge, casting long, soft shadows that seem to float in tandem with the weave. Between them, a low-slung table carved from a single block of raw, porous travertine introduces a grounding earthiness, its pitted surface a stark, beautiful contrast to the smooth, almost digital perfection of the crystalline rug fibers.

Curated Design Elements for Coastal Equilibrium

• Furniture Pairings: Sculptural, white-washed rattan seating; low, monolithic travertine block tables; organic hand-molded clay floor vessels.
• Textile Synergy: Sheer, floor-to-ceiling linen curtains in a chalky, off-white tone that flutter with the coastal breeze, blurring the line between the interior and the exterior landscape.
• Lighting Philosophy: Indirect, recessed perimeter lighting that accentuates the “hover” effect of the anti-gravity bohemian rugs, making the floor appear to lift away from the structural foundation.
• Accent Palette: Driftwood greys, sun-bleached cream, salt-mist white, and deep, resonant cerulean.

The air in this room carries the scent of brine and sun-baked stone, while the visual weight of the space remains impossibly light. By avoiding heavy metals or harsh, dark woods, the focus remains entirely on the relationship between the crystalline weave and the natural horizon. The rug acts as a meditative platform, its haptic fibers gently vibrating at a frequency that mirrors the ebb and flow of the tide. This is not merely a room for living; it is a space designed for the cessation of external noise, where the only transition is the shifting light across the azure gradient of the floor.
