"It is faster with asm.js optimizations, but as other comments mention, it also runs well (depending on CPU/GPU) even without such optimizations, in browsers that have no special asm.js optimizations whatsoever." Actually, that's not true at all. That's the plan for asm.js, but this demo doesn't run in anything other than very new Firefox builds, AFAICT. It crashes chrome, IE doesn't support WebGL (yet).
