Our very own Tagtool
Completed building a TagTool Mini on 6 March 2010, with Adam Perfrement. Haven't done so much soldering in years. We used a plastic, tupperware-like case temporarily; it ain't pretty, but it works! The TagTool follows on from Laser Tag, and also uses tagging and projection. It is a live "digital drawing" and animation application. Visit http://www.tagtool.org.
