If you can hold the finish date off until at least the end of this month, I'd happily join in.
A plethora of projects is eating up all of my time at the moment, but I should be able to fit something in from the end of next week.
A robot themed competition would be cool. Big robots stomping buildings, nanobots forming shapes, robots with laser-eyes, fighting robots, robots that build other robots - etc... There's loads you can do with them!
