Along the same lines as the Hipster PDA, PocketMod is a paper-based organizer. You use a Flash application to arrange page modules onto an 8-page layout, then print the whole thing as a single sheet of paper. Then, with a nifty cut-and-fold technique, you end up with a mini organizer that fits in your pocket.

D*I*Y Planner is a similar idea, more open-ended, but without the nifty Flash and origami flavor.
