I’ve really been enjoying Google Chrome, the web browser created by Google which features the “blazingly fast” V8 JavaScript engine. To show off the features of the JS engine, they’ve created a site called Chrome Experiments (via Google Blog). There’s some really cool stuff there (check out the Browser Ball demo), but I think my favorite is Ball Pool… it’s fun and it makes cool looking paterns! There’s also a few neat 3D demos.
I’d recommend checking them out, though you may need Google Chrome or a late version of Firefox or Safari to view them.
