I posted a video of this in late May, but now that I've had a chance to document a few things, there is more information online.

It's based on an old touchtone telephone keypad, a rotary encoder, a two digit LED display, and a USB-based AVR breakout board (the Teensy++). The PC board was hand-etched at home, and it's mounted in a solid white, repurposed jewelry or makeup box, purchased at the Goodwill.

We used this both at toorcamp and at the Someday Lounge performance thing on July 17th.
