Google released a site of browser games to showcase Chrome's javascript capabilities and all (to coincide with the release of Chrome 2.0). I don't have Chrome, but some of them at least work in Firefox. Others choke in Firefox, but when Firefox 3.5 or whatever comes out we should see an improvement.

Browser ball is cool... you can bounce a ball around inside multiple windows you position next to one-another.

I like Chrome but I feel dirty using it.

I don't trust Google any more, so I don't trust their browser. Their 'do no evil' thing has been subverted by corporate power. However, my coding skills are improving daily. Since the thing is open source, once my c++ skills are a bit improved I'll probably grab the source and make my own version without any hidden tracking capability. That may be awhile yet, though.
