Probably best known for his work on altered books, Brian Dettmer also works with altered cassettes and video tape. His work is meticulous. For one piece described in the video, he took over 10,000 photos of the work in progress. The result is an animation of the piece coming alive. His work is being show in galleries in New York, Chicago, San Francisco, Barcelona, and Atlanta. View more of his work on his flickr page.
