I just read about this in a blog post by Rob Relyea.  It's a cool facebook client written to show off some of the features of Windows 7 and WPF/XAML.  I just downloaded and installed the app, and after a little poking around, I really like it.  It's clean, responsive, and easy to use.  I don't hate Facebook's web interface, but I do sometime have problems with images not loading, or screens loading half-way and never finishing.  So far nothing like that in Fishbowl, but I'll keep you posted.  Check it out here: http://www.fishbowlclient.com/

Anyone else tried this app or similar apps?
