That's the thing, though. (If it were finished) You'd have to put it somewhere in an existing category, and software would have to be it until there were enough other similar projects to create a new category. Hell, look at the small size category so far (I'm sure it'll get broken up, but...) there is a wide range of types of projects represented in that category so far. Speaking of... Pinball Unleashed is thrown in the small size, yet v-pins are defined as full size.
