Looks very similar to the way Coconut Island is set up with a PC interfaced through a driver board. The input side is also done on that board (CI used an IPAC for input and a custom driver board for output). It's exactly the concept Nug and I spoke about - produce a kit at that level for people to develop their own games. Glad someone has done it - we lacked the programming expertise to make it work, this looks really interesting.
