sandboxels
The falling-sand physics sandbox in your browser: 500-plus elements reacting freely across chemistry, circuits and construction.
How to play
Choose a material from the element bar and paint it onto the canvas; everything reacts by rule — water plus fire becomes steam, acid eats through metal, current travels. No goals, no win state, pure sandbox.
Mouse — pick an element and draw on the canvas.
Integration notes
A sandbox with nothing to win keeps people around far longer than average, and user-made creations pile up on their own. It's on the heavy side (plenty of element textures) with a deep ruleset — embed the whole thing in an iframe rather than forking the code.
