I'm a huge nerd. Zen is nerdy and I think that's part of the reason I love it so much. What I love even more is the intersection of really geeky/nerdy things with Zen. In that vein, I recommend this book:
The Dharma of Star Wars
... not really as a "serious" Buddhist book, but just as a fun geeky read.
I also really love the 8-bit Buddha and the An.Ja.Li (Gassho) emoticon badges from Buddha Badges:
Anyone else want to fess up to some nerdery?
