Google launched a new toy today. The Quick Search Box looks good so far and the lead developer is the guy who was/is behind the magical QuickSilver so I have high hopes for it.

I had to wait til I got home to try it, but it's worked well for me. No crashes to report as yet, but I've only been running it for a few minutes. I like the appearance as well, but I hope they add a second or third pane ala QuickSilver.
