Curious Inventor has just released the Stribe touch LED controller project as a modular kit –

Each Stribe1 has a touch strip and double column of LEDs that can display and control music and video programs. Multiple Stribe1’s can be daisy-chained together to form a low-res, multi-touch display. Use with Max/MSP or other software to adjust track volumes with VU meters, make a sequencer, control synth params and pitch, “scratch” through sounds, etc.
