Once in a while I get focused and read an entire book in one day, but it's got to be an easy read with a nice font and some pictures, and Nancy G. Heller's slender book Why a Painting is Like a Pizza: A Guide to Understanding and Enjoying Modern Art fit the bill-- it sheds some light on Mondrian and those ridiculous white canvasses and weird installations and Damien Hirst's shark in formaldehyde (The Physical Impossibility of Death in the Mind of Someone Living) and though I don't buy everything she says, it's a nice tour through post-modernism: one urinal out of a possible fish.
