WebGL water ray tracing demo

I always like a nice real-time ray tracing demo, especially when it involves physics. Evan Wallace released a very impressive WebGL demo featuring real-time raytraced water with caustics and physics (waves, buoyancy).



The demo is playable (Google Chrome browser required) at http://madebyevan.com/webgl-water/
