Chrome Experiments has been around for a few years, but continues to garner attention as a playground for HTML5, canvas, and javascript experimentation. Programmers and designers are invited to submit any experiments that push the boundaries of interactive design for web, knowing full well that they probably won't work on all browsers. What a freeing concept! Especially in a time where clients are still asking for cross-browser compatibility (argh to IE...).

Anyways, here is a brief round-up of some cool examples of JS usage! May it serve as inspiration for anything you're working on now... for me, it is inspiration for visualization possibilities in the ed realm...

Impress.js
Impress.js uses HTML5, canvas, and JS to create prezi-style slides. AND it does so with 3D-like depth effects (Prezi can't do 3D).
Downside: It doesn't work on my iPhone; you will be directed to a more traditional view of the slides. It also doesn't work in early versions of IE (but that is no surprise). But if only...
