Overtar - easy URLs to Twitter, Gravatar, Digg & Facebook avatars

When I put in one of my most commonly used account names (mgrinich) a photo of David Hasselhoff comes up.<p><a href="http://overtar.appspot.com/mgrinich" rel="nofollow">http://overtar.appspot.com/mgrinich</a><p>This is awesome.

Brilliant. I hope this ends up being used everywhere.
