It is always a challenge for every musician to get heard. A lot of people will post videos on YouTube, but they are often as boring as watching someone hit the Play button. Dharmatronix had the clever idea of making a simple music video using the iPad apps TouchViz and Vjay. The music is from "a combo of ipad and cpu", but you won't see any of that. Just the Danger Bot!
You can find some videos of the actual music making progress on his YouTube channel as SpaceAje.
