Today is the anniversary of the death in 1993 of avant-garde film maker Paul Sharits. His web site has a short biography written by his son, who mentions the bi-polar disorder which runs in his family. A number of his films can be seen online at ubuweb. There are some still shots and discussion of Sharits' technique and philosophy here. CanyonCinema has an annotated list of his work.
