Exciting books for artists

What are you reading?

I'm reading Geral Weinberg's "On Writing: The Fieldstone Method". Has very straightforward and approachable advice for getting past writer's block, gathering and finding the bright shiny things that you can assemble into your new work, and bringing a workmanlike attitude to the artistic process. I think it has applications for the visual arts, as well.
