Several things, all at once. I have more involvement in some than other:
1 (My pet project): Lead my 4-man (actually 3-man and 1-lady) team in designing and constructing a pair of tandem recumbent bicycles from the ground up.
2: Finish hovercraft prototypes and make 4 people's worth of rideable hovercrafts
3: Redesign and mount air cannons onto aforementioned vehicles.
The tandem bicycle idea is the one that's gonna really get off the ground (hopefully it'll stay on the ground once its built

). I've been studying many designs of both tandem and recumbent bicycles, as well as a few existing designs. Me and my electron-cough-design team are all convinently learning how to TIG weld right now too....
