Per request, here are some pictures of my micro-m0dule for the Chaos Communication Camp r0ket-badge:
This is probably the simplest possible m0dule one can build. I only used left overs: A white smd-led, a smd-resistor, a little bit of perfboard and a few wires.
Every attendee of the Chaos Communication Camp 2011 get a r0ket-badge. It is possible to enhance the 5-way-switch to get a better look an feel by using a 3D-printer to manufacture a nipple-mouse for it.
Here a some pictures of the r0ket with and without the printed cap.
You can get the .STL at thingiverse.com and print your own:
