Drawing a flow-diagram for the Formula Flowcode Buggy and simulating it in Matrix Multimedia's Flowcode 7. The drawing finishes at ~3:20; you may want to skip forward to there once you have seen a bit of the editing.
The program moves forward, turning left halfway through, and changes the LEDs. Mistakenly, the first run omits any time for the second forward move, so this is added later.
Software: Flowcode 7.2.1.4 on Windows 7.
