Left-drag paints the selected material into the world at the voxel under the cursor. Right-drag orbits the camera; scroll or + / − changes brush size; arrow keys orbit; space pauses, S steps one frame, C clears.
Fire rises, spreads and burns wood, oil and plant down to ash. Lava melts ice, ignites fuel and cools into stone where water touches it. Water drowns fire to steam and sinks through oil. Stone and metal sink through liquids, wood and ice float. Steam condenses back to water, smoke fades out.
A real Gray-Scott solver. Eight regimes - mitosis, coral, worms, solitons, fingerprint - and the feed/kill map that makes them.
An explicit leapfrog finite-difference solver. Resonance, standing waves and superposition, with the measured period next to the theory.
A soundboard of 25 sounds, all synthesised live in your browser with Web Audio.
27 elements, density physics and real pair reactions — pour, ignite, dissolve, grow.
