Last year, we launched the first touch Twitter application for Windows 7. Since then our obsession with touch, Twitter and 3D user interfaces has continued. Okay, maybe it has gotten a little worse, but it has allowed us to work on some really fun stuff!

We recently had the opportunity to create a Twitter mashup and are excited to bring you Touch Twitterworld in 3D.

The 3D Twitterworld app first premiered at Earth Day on a giant touch wall (courtesy HP). It will soon be offered on the web and as a download for all the fanboys.
