When he’s not working, he finds enjoyment in 3D printing, pinball, games (board & video), geocaching, craft beer, B-movies, science fiction, trivia, and traveling. He lives in Cary, NC. Tom is also known as “spot” by many people in the open source universe, he’s gone by that nickname since the 1st grade, and he happily answers to it.
