A Pen by Chris Roche.

Prism

HTML5 Canvas based animations reminiscent of the Bezier screensaver from Windows. Essentially, it is a bunch of triangles of random color/opacity whose vertices translate independently. Tweak the values at in the config object at the top of the JS editor to affect the number of triangles, the speed of the animation, and the color pallette used.

Thanks to Paul Irish for his article on requestAnimationFrame (http://www.paulirish.com/2011/requestanimationframe-for-smart-animating/), and Bob Nystrom for his book on Game Programming Patterns (http://gameprogrammingpatterns.com/) which inspired the loop logic for this pen.
