A lot of different genre's peak my interest for model building, but predominantly Robotech/Battletech mech's, aircraft, and Star Trek. I would really like to build a wearable papercraft costume for halloween at some point, but with two small kids, a full time job, and a part time job, I don't think I would have the time for all the extra fiberglass/epoxy reinforcement that most people seem to do to those types of outfits.
