I really love the use of overhead projectors to create live moving art, as done by such artists as Daniel Barrow, Shary Boyle, and Kara Walker. I've demonstrated it, with varying success, to undergrad classes in the past. This term I assigned the graduate film students to do a performance. It was quite delightful to watch. Of course I needed to critique them and realized only when faced with the task did I realize that I'd established no real criteria for success and wasn't sure what do say (of course I didn't let doubt actually slow me down). Pictured above, An, Xin, and Jingyi with the projector.
