These ones answer back — an eye that tracks you, spacetime on a throttle, light that moves to your music.
Six real minds under one scanner: human, T. rex, mammoth, dolphin, raven, octopus. Real anatomy, real neuroscience — fear lights the amygdala, sonar wakes the melon, camouflage ripples an octopus's skin. Drag to orbit, probe a region, switch species.
Six unsettling specimens recovered from a derelict survey array — an eye that tracks you, a figure in the static that edges a little closer each pass, a terminal that types back. Eerie on purpose, so it’s one for teens.
Glowing orbs with a gravity dial — rain them down like marbles, or flip to N-BODY and let every orb pull on every other until orbits form. Drag to fling. Click to spawn.
The original — blue-and-ember orbs on the Matter.js engine, preserved as born (with the fonts freshened). Click to add, drag to fling, let them rain.
A constellation that talks to itself — nodes drift, links weave, and signals race the web. Push it around, spawn new stars, or flip GRAVITY and pull the whole thing to your hand.
The first spark — the original experiment, preserved exactly as it was born. Blue-and-ember stars, pure drift, click to add more. The Signal grew from this.
Four motion pieces that lean toward your pointer — a holo-card that catches the light as you move, aurora ribbons, orbiting things, and a line that refuses to behave.
Push the throttle and watch spacetime give way — a warp-field flight deck with honest physics under the glow.
Drop in your tracks and let six scenes move with the sound — a full-screen light show for the music you've been generating.
Drag to paint with light — flow, explosion or gravity-well physics, six hands-off auto-play patterns from rain to fireworks to a flocking swarm, and fifteen color palettes to play with.
The northern lights over a still mountain lake. Drag to bend the curtains, tap the sky for a flare, tap the water to send ripples through the reflection — or leave it alone and a hidden hand keeps them dancing. “Merry Dancers” is the old Scottish name for the aurora.
Hundreds of neon wisps drifting on an invisible current. Chase them and they flee; tap and they scatter like sparks. Named for ignis fatuus — “foolish fire”, the will-o’-the-wisp of old stories that dances just out of reach.
Eighty glowing particles on elliptical orbits, leaving fading trails that bend toward your finger. The first page on this site built end to end by GPT-6 Astra through Codex, briefed and checked by Claude.
