Alpha Clock Five Turn Signal

From the forums:

Guy Albertelli wrote in with an unexpected use of his Alpha Clock Five kit: a turn signal machine for the back of his Xtracycle-- complete with a "SORRY" button and a random-scrolling-message mode (that isn't shown in the video). There's even a clock mode with an improvised "second hand."

One might argue that the scrolling messages could be a little simpler, but that's really missing the point: this is an awfully clever application for a bright and self-contained alphanumeric LED display.

Guy's video is embedded above. (YouTube link).
