Worlds of WebGL video
WebGL is one of the most powerful additions to native web technology. The move from Flash to Canvas in the 2D rendering scene was something very big, but WebGL, the 3D context for canvas, completely overshadows it. Its semantic equality with OpenGL ES and its ability to tap into the raw power of your graphics card is not something to be ignored. I have captured a video of the amazing Worlds of WebGL demo by Jacob Seidelin.
