Paint 27 kinds of matter
Water, gel, oil, mercury, acid, nitro, rice, rubber, wood, stone,
metal, ice, lava, fire, smoke, steam and more — every material
behaves differently. Ice melts. Wood burns to ash. Steam condenses.
Nitro does… what nitro does.
Build machines that run
Weld strokes into rigid bodies, pin them on axles, drive them with
jets, stretch rubber into slingshots, or take the controls yourself.
The arrow keys can drive what you paint.
Import anything
Drop in any PNG.
It becomes matter.
Your drawing. Your logo. A photo of your cat.
Rigid. Liquid. Flammable.
Whatever you choose.
Old OE-CAKE .oec scenes open too, preserved exactly.
Rewind time
The engine is bit-exact, so a session is a starting state plus your
inputs — which means file sizes stay lightweight. Replay it, scrub
it backwards, share it as a link that provably reproduces the same
world, bit for bit.
Classic Mode
One toggle and the toolbar becomes OE-CAKE's, laid out exactly as
you remember it — same toolbar, same buttons, same order, same
muscle memory, fifteen years later.
Built on SunaEngine
Every simulation in SunaBox runs on SunaEngine, our open-source
deterministic physics engine. Curious how it works?
