Iris: more HTML5 Canvas pixel manipulation fun

After I wrote the plasma effect quite some time ago, I wanted to give it a shot at improving the performance of such a pixel manipulation demo. And so I wrote a similar demo called Iris that will generate a random sequence of patterns and effects each time you run it.

The result is quite impressive when running in Chrome on my Ubuntu laptop with full HD resolution, where I get 60 FPS consistently. Unfortunately, Firefox achieves only just above 30 FPS, while Opera gets just under 30 FPS. Enjoy the Iris live demo yourself.
