This gorgeous prop -- which is powered by the Propeller, of course -- was built by my friend, Matt Hawkins (www.likeform.com) for Midnight Syndicate (www.midnightsyndicate.com). It uses an EFX-TEK HC-8+ as the controller with a SEETRON 4x20 OLED dsiplay (on front), NeoPixel strips for the tower, and a bunch of my drivers that Matt knitted together. There are a variety of switches an pots on the front that change the behavior. The production wanted the device to look "home built" and Matt did an excellent job of that, going so far as to use old-school Dymo labels for the switch and pot markings.
After the film was shot we added a remote control for the live show. The remote is an XBee radio, batteries, a pot, and a button. The Propeller uses the internal XBee to do a Remote AT command to read the pot and button from the remote XBee -- works really well and kept the remote unit very simple (no programming, just XBee configuration).
