Went by Book Guy, browsed around, saw some art books. Ratha had raved about "Drawing on the Right Side of the Brain" yesterday, and so I looked around for it idly, not at all expecting to find it. Just at the very point of giving up, however, its title popped out at me from an otherwise unassuming paperback spine. $6.50 later I started reading it over dinner. Good stuff.
Now I am realizing that trying to hack up a little dynamic programming algorithm is just too taxing for my 11:30pm brain.
