Executive Dysfunction — Probe whether an AI model can tell which chess positions deserve deeper thinking, given a finite budget of hand-offs to a deeper instance of itself.
Fourier Bloom — A tiny transformer learns clock math in your browser.
Replacement Model — A tiny transformer invents Pokémon names. Then its MLPs are removed and sparse transcoders imitate them in place. It still speaks. Live on WebGPU.
KataGo — A real KataGo network (b6c96) playing full-size Go in the browser. 1.16 MB of weights, compiled to WGSL by tensorgrad.
Hilbert allrgb — All 16,777,216 RGB colours, each exactly once: a Hilbert curve through the 256³ colour cube unrolled along a Hilbert curve filling a 4096² square.
Chameleon — A neural cellular automaton grows a chameleon from one cell on your GPU, using weights from the paper “From Cells to Pixels”. Scratch it and it heals.
Regrow — A neural cellular automaton grows a 3D donut from one cell, trained live on WebGPU with the Cells-to-Pixels recipe.
Maxwell's Equations — Interactive, animated walk-through of Maxwell's four equations — Gauss, no-monopoles, Faraday, Ampère–Maxwell — building to how E and B become light.
Lie Group Ladder — The ladder to a Lie group: climb from a bare set through manifold and group to a Lie group, watching the same objects reorganize at each rung.
Legalize — Translate legalese into plain English with Word-style margin annotations.
Purrvana — Purrvana - Fall asleep to a cat purring.
Earthquake Depths — A translucent 3D Earth with a year of earthquakes plotted at their true depth beneath the surface.
Simulated Brain Argument — Animated step-through of the computability argument against biological naturalism: simulate a brain, ask it if it's conscious, and follow the logic.
Clean Text — Clean up dumped text — strip terminal artifacts, reflow lines, fix whitespace. AI mode handles arbitrary mess.
Sierpinski Flow — Interactive visualization of the bitwise art formula (x & y) % (y - x) % 37, producing fractal interference patterns from Sierpinski-like structure modulated by diagonal banding.
Decision Theory — LLMs play classic decision theory problems: Newcomb's Problem, Parfit's Hitchhiker, and more.
Ask The Angels — Ask the Angels - Seek divine wisdom for your mortal business problems.
Points of View — One statement. Every take. See what the most relevant intellectual tribes, disciplines, and stakeholders would predictably say about any given claim.
The Twits — Dramatize any conversation: boring parts removed, subtext made overt, and honesty cranked up to 11.
Messiness — How automatable is your job? The Messiness Index scores jobs across 6 dimensions of task complexity. Higher messiness = harder to automate.
Mobius Progress — Mobius progress - man walking the Möbius strip
Mobius Gears — Gears on a mobius strip create an illusion where because the entire strip is rotating, alternating gears seem to be turning faster/slower.
Winter — Code snippet ported from the artist @KilledByAPixel. Check out his stuff
Jellyfish — Code snippet ported from the artist @yuruyurau. Check out his stuff
Newcombs — Explore how predictor accuracy and payoff ratios interact in Newcomb's problem. Two-boxing only wins when prediction is no better than chance.
Spinning Fan — A hypnotic multi-colored spinning fan.
