You might be interested that musician David Byrne makes art with powerpoint. With a completely differing view, information designer Edward Tufte tells us that PowerPoint is just a bunch of decorative special-effects.

I went to E. Tufte's seminar when he was in New York last fall/winter. He's a really great speaker and his books are quite fascinating. One of the most memorable things I remember from his talk was about how bad powerpoint is. At the same time, he was talking about apple as if they were his sponsor (but not). His books are all very interesting as well. We were lucky to get the whole set at the lecture series. It's interesting because I've gotten a couple of presentation freelance job requests for some small projects. They were for people who wanted "cool powerpoint-like presentations but not in powerpoint (flash)." I didn't do them.
