Google's Chrome Experiments lab showcases some interesting uses of Javascript.

We think JavaScript is awesome. We also think browsers are awesome. Indeed, when we talk about them, we say they are the cat's meow – which is an American expression meaning AWESOME.

In light of these deeply held beliefs, we created this site to showcase cool experiments for both JavaScript and web browsers.

These experiments were created by designers and programmers from around the world. Their work is making the web faster, more fun, and more open – the same spirit in which we built Google Chrome.

Some pretty slick stuff in there. Check it out. You won't need Chrome to play with these experiments.
