Be sure your sound is turned up! In the early 1990s, several years before I developed this piece, Chuck E. Foltz at the Pittsburgh Childrens' Museum commissioned my friend and colleague Ben Carter to build a real, physical machine that actually made music in this manner. I always felt that a "virtual DMC" was a great idea. When I discovered the interactive capabilities of Macromedia Director™ I set out to teach myself to make one.
