Fascinating and poignant article in today's NYT about an artist who painted self-portraits to document the progression of his Alzheimer's. Be sure to check out the slideshow; by the end of the sequence he's barely even recognizable as a person.
The first thing I thought of was the cat art of Louis Wain, and William Kurelek's incredible, Bosch-like painting, The Maze, two dramatic examples of the profound effect that mental disorders can have on the creative process. And yes, they both were in that Time-Life book on The Mind - what of it?
Anyway, I don't really have a point, except that I think this sort of thing is really cool, but at the same time I feel kind of ghoulish and guilty for doing so.
