Here is a great Interview done by Gretchen over at Gearwire.com with an Interface Designer and Builder Rui Pereira who created an experimental controller as part of his thesis. Usually controller videos are of not much interest atleast to me, however this one was fairly captivating because Rui talks about the actual design of the controller and why it was made that way. He also demonstrates why it was called the Transformable Uber Interface for Stardom and points out the obvious Guitar Hero and other video game inspirations. Enjoy.
