Bjork stopped by the Colbert Report last night to talk about her new album "Biophilia," which has an interactive iPad component that lets listeners manipulate the music with various on-screen elements. The interview wasn't without the obligatory technical difficulties, but thanks to some expressive gestures we all came away enlightened as to the difference between a mouse and a touchscreen.

As a rider to this post the tech for the Reactable that was developed for Björk's Volta tour is also available on the ipad - and it is much more fun than the Biophilia album. You can also use it to make actual music.
You can purchase the app for around 10$ or get the table custom made for.... somewhere around 12K.
