Swiss sculptor Jean Tinguely used to make machines that created abstract paintings. The machines themselves are quite nice to watch and work as art in themselves. Take a look.
Blarg. Sometimes this book has a lot of interesting things to say, which kept me reading. A lot of the time, they're just blandly listing off as many artists as possible. This is a very frustrating book, because it could have been really good if the authors had just focused in a bit more.
