Absolutely fantastic. Although I'm a bit bitter: where were all the great graphics frameworks back when your only choice was native code? There was Processing.

Absolutely fantastic. Although I'm a bit bitter: where were all the great graphics frameworks back when your only choice was native code? There was Processing...and recently Cinder and openFrameworks. Only very recently. Once OpenGL moved to the web, we got Processing.js and Three.js and PhiloGL and some others in a fraction of the time. I guess it was too difficult to make a framework that worked across operating systems. So now that high performance 3D graphics are on the web (which is the closest we've gotten to "write once, run anywhere"), we can expect to see a lot more.
