[sudo-discuss] light-up disco dancefloor

Tue Oct 28 12:41:45 PDT 2014

Side note: I also was thinking of building a Sudo Cube sculpture with
controllable LEDs to hang in the space above Sudo Room.

We could teach people to program by having them control the lights on it!

easy Python example

someone made a Node library also
