I was involved in authoring software plugin allows Macromedia Director Lingo to control an EZIO Board, developed at the University of Michigan School of Art and Design by Micheal Rodemer and Ed Bennett in order to make circuitry and computing much easier for artists. As the board is meant to make things easier, so it the EZIOXtra. I wrote the PC version in cooperation with Ben Chang so that we could use it in UCLA Tangible Typography class, in which sensors control onscreen type as one of the final assignments. The Xtra makes it unnecessary for students to learn serial port programming. To get a list of functions, type: put interface(xtra "ezioxtra")
The EZIOXtra is a Windows port of the original Mac EZIOXtra written by Ben Chang.
