33 generative loops that turn a small LED panel into a gallery of Amazonian graphic systems. Everything moves, everything loops, nothing repeats the same trick twice.
A Divoom Pixoo-64 is a 64×64 LED matrix — 4,096 lights, usually showing clocks and 8-bit mushrooms. The experiment: treat it as the smallest art gallery in the house.
Amazonian geometry. Indigenous graphic systems from ten different traditions, studied for their logic — not copied as ornament.
Black is always the background. Colour comes from a fixed pigment-born palette. Every piece flows forward — always moving, never a slideshow.
Each loop does a single thing: march, orbit, breathe, cascade, wind. A gallery works when the pieces don't shout over each other.
Three questions before drawing a single pixel: which patterns survive a 64-pixel grid, which colours survive an LED panel, and how does a loop actually close.
Thick, modular systems: Baniwa basketry weave (literally a grid), Marajoara meanders and spirals, Wai-Wai diamond scales, Kené labyrinth lines, Yanomami checkerboards. Their logic maps 1:1 onto pixels.
Fine parallel hatching (Asurini, Kayapó body painting) turns to moiré noise below 64 pixels. The lesson: borrow the logic — the axis rules, the border bands, the block fields — never the fine line.
Shrink any design to 16×16 and squint. If the silhouette still reads, it will read on the panel. Half of every draft failed this test and went back.
Urucum (annatto seed), jenipapo fruit-black, clay whites, forest greens — crossed with 2026 colour forecasts, which happen to be heading exactly toward earth and teal. Twelve colours, locked.
An LED that isn't lit is true black — infinite contrast, for free. So black is reserved for the background and never used as a drawn colour.
Below roughly #202020, gamma correction renders every value as the
same black. Real jenipapo is #16202B — invisible. It ships lifted to
#3A4A5C.
LEDs separate hue far better than dark values. So depth ramps step sideways through the palette — urucum → ochre → straw — never “same colour, darker”.
A 1-pixel line survives the bare panel but dies under a diffuser. Everything structural is 2 pixels or more.
Three acts, one honest failure in the middle.
Ten pattern traditions were redrawn as a procedural atlas — each one by its geometric logic, at full resolution and again at a true 64×64, to see what survived.
The atlas swatches became the design source for everything after.
First motion attempt: keep the pattern still and slide a brightness wave across it. Technically seamless. Visually dead — “nothing really happens.”
The lesson became the project's core rule: light travelling isn't motion. Structure travelling is.
Every pattern was rebuilt from zero as pure shader mathematics in Blender — no images at all. Now the rings actually crawl, the scales actually march, the markers actually orbit.
One mechanic per piece, thirteen mechanics total, so the gallery never repeats the same movement twice in a row.
A study of 28 classic mask loops gave the motion grammar: 1-bit thinking, fat continuous fields, and a tiny change per frame — the smoothness lives there. Applied here with one inversion: where mask work flips black and white, this project keeps black sacred and shifts hue hierarchy instead.
Every loop closes by construction, not by luck.
A single value T runs 0 → 1 across the clip, keyed one frame past the last rendered frame. Every moving field is frac(k ± T) or sin(2πT) — so frame 91 equals frame 1, exactly. No seam to hunt.
The Pixoo's practical ceiling. At 15 fps that's a six-second cycle — long enough to not feel like a short repeat, smooth enough to feel continuous.
Colours are snapped to the 12-colour palette after render — no in-between tones can exist. A verifier then measures panel coverage, colours used, and compares the loop's wrap delta against the average frame delta to certify it seamless.
A ring of alternating-colour markers that rotates an odd number of slots per cycle lands with its colours swapped at the wrap. Rotate an even number, always.
In a piece that drifts N cells per cycle, colour can never depend on the cell index along the drift direction — at the wrap, every colour rotates. Colour by the perpendicular axis instead.
The project has a generative-video companion route (a 34-prompt catalog for Seedance). Its most useful finding is an inversion:
Ask for “pixel art” and you get an image pixelated on top — soft edges, dirty palette. The panel already downsamples everything. So the prompts ask for clean, flat, high-contrast geometry on pure black at full resolution — and let the reduction happen on the way to the panel. Vector-turned-pixel reads far better than raster pretending to be pixel.
// the constant block, appended to every prompt Pure black background, RGB 0,0,0, no gradient, no vignette, no ambient glow, no fog. Flat emissive colour fields only: no shading, no lighting, no cast shadows, no reflections, no depth of field, no motion blur, no bloom, no film grain. Perfectly centred, symmetrical, the motif fills the frame edge to edge. Constant velocity throughout, no easing, no camera shake. Seamless loop: the final frame must be identical to the first frame. Limited palette only: pastel sage green #A9C484, pale celadon #CAD3C1, deep moss #6B7F5C, annatto red #D4442A, ochre #C8933A, warm off-white #EDE6D8. No text, no logos, no human figures, no animals, no photographic texture.
// sample — the highest-hit-rate loop request (rotational symmetry is arithmetic) A single large rosette filling the frame on pure black, built from a continuous labyrinth line of uniform thickness that folds back on itself in right angles, never crossing, never ending. Eight-fold radial symmetry. The whole rosette rotates clockwise at a dead constant speed and turns exactly 45 degrees over the clip, which returns it to a state identical to the first frame.
The 33 finished pieces, though, were all built in Blender — where the loop is mathematics, not negotiation.
Every file below is the real 64×64 GIF that plays on the panel, scaled up with hard pixels. Lit % is how much of the panel each piece switches on — the gallery breathes between 8% and 61%.
Indigenous graphic systems are semantic — kené encodes song and vision; body painting states family, role and rites. These pieces reference the geometry’s logic (concentric squares, meanders, symmetry with deliberate breaks, the urucum/black/straw triad) and reproduce no specific community’s pattern. Brazil’s PL 3909/2024 proposes recognising indigenous graphics as collective intellectual property; Peru declared kené national cultural heritage in 2008. If this work ever goes public or commercial, the right move is commission and benefit-sharing — following precedents like Refik Anadol’s Winds of Yawanawá, where 100% went to the Yawanawá institute.
