A nice work by Nicolas Villar at the Embedded Interactive Systems, Lancaster University UK:
VoodooIO. Basically it is on designing User Interfaces build by knobs, sliders and other one-finger stuff on an conductive fabric. The project evolved out of the Pin&Play project which provides the one-pin technology to communicate with the computer.
The result is as WmMnA says “[...] a bit like you have this home entertainment system and instead of using a giant remote control you just pin a few buttons into your couch to control it.”

It’s a bit like having all the modular controls as they appear in my JInT classes as hardware pins.
