One impressive project I neglected to include in my highlights from NYU's Interactive Telecommunications Program 2010 Spring Show is Scrollables, a series of multi-scroll devices exploring "possible applications for a paper-based tangible interface." Here, you can see that interface adapted to play games like Pong and Space Invaders.

Creator Filippo Vanucci explains the concept:

"As paper as a medium is more and more threatened by the introduction of portable multi-touch screens and e-readers, the project aims at bringing back the tactile relationship with this material as a way to interact with the digital world.

Playing with the metaphor of "scrolling" adopted by early research in Human-Computer Interaction, the mouse wheel is replaced by physical scrolls. The end result is a series of boxes and table tops with movable rolls of paper wrapped on their surface, which allow for an interaction with digital applications in new and yet familiar ways."

If you'd like to create your own Scrollables, Vanucci has posted instructions on how to build your own multi-scroll devices, and plans to upload software and sample applications in the future, on his site for the project.
