I make models. Metal Earth has some very nice aerospace ones [1]. Guillow's makes some amazing balsa wood models -- if you really want to, you can put RC engines in them and they'll really fly [2]. I currently play with Estes Rockets, but want to get into amateur rocketry like this guy who built a model Falcon Heavy with onboard navigational computer and engine gimballing [3]. Every Christmas, I add one more model building to my seasonal train set.

I'm also into photography, graphic design, videography, fishing, surfing, and backpacking. My wife's paints.
