Flipdot display with drawing, games, etc.

Here's the cleaned-up version of my flipdot display (made by Alfa-Zeta Ltd.). I use my custom Android app to draw to it, show the time, and play some games. The display is driven with an Arduino with a bluetooth serial port, and I send commands to it with my phone. Some technical details about the build: http://www.scottcutler.net/projects/f...
