seen a lot of these, but this is actually interesting for a change... not just a copy of something we did 15 years ago on ancient hardware. the simulation using renderbuffers and float textures is cool - although the method used is ancient unexciting technology (see the water effect in winamp avs which uses the same trick in software 15 years ago) it makes sense from the webdev perspective of 'javascript is damned slow' - infact probably far too slow to do even attempt to do this CPU side. the caustics are much more interesting though - firstly because i didn't know the trick already or re-invent it during my career or even know about the OpenGL ES extension that makes it practical (which is very very old on Desktop and very generally useful). its always cool to see some raytracing logic applied with some cleverness applied to get some more mileage out of it at real time...
