For me, I like building and painting models; tanks, fighter jets, Gundams. I like to paint them up and make fictional unit names. Im actually studying SolidWorks so I can learn to design custom design turrets for my tanks, and create fictional hypothetical designs.
I also fly RC planes, just got into RC rock crawlers.
Wifey always talks about how expensive my hobbies are getting, but these are the few things that takes my mind off of my really stressful job, and spurs my imagination.
What about you guys?
