Creativity Inc., by Pixar co-founder Ed Catmull. A funny and insightful book that should be required reading for any technical leader who works with artists/designers.
Separately he gives good evidence of what an A-hole and tyrant Steve Jobs was. Most won't talk about it out of politeness or concerns for their network. Having worked for a psycho at one time, you know how others shade their language when discussing. Very entertaining!
