This is, what the new TwittFont widget looks like. The (german) homepage of the new copperation between a german font provider (FontShop) and an agency (Moccu) provides a very simple way of configuring your own.
Even if you can't read german. This is basically a four step process.
1) Enter your search word or username
2) select display font
3) review the animation
4) select size and copy the html embed code
To me this looks awesome :) Even if it is flash :)
