2012-09-11: Started working through checklist, needed a bunch of changes to make IR emitter/detector line up.
2012-09-09: Started board layout.
2012-09-08: Put together BOM and designed schematic for the strip board containing 5 LEDs, the drivers for them (WS2801), the IR emitter/receiver, and the ADC/logic for the IR.
Wednesdayish on the playa: Started throwing around ideas for 2013's project.

Random Thoughts

Tic Tac Toe game in lights on the playa
Jumping on a square makes a move
X/O indicated with colours instead of symbols, as it would be harder to design LED symbols that could be jumped on
IR sensors used to detect people's location?
Strips of LEDs/IR sensors run in clear tubes like the Man perimiter's LEDs
Hubs located at cross points which have high powered LEDs
All run off the StrichLux system the same as Beacon4
