Before I began working on TAG, a friend and I were using the Robit Studios name in an attempt to have a t-shirt empire. Although it was a lot of fun, and there was much success along the way, it was harder to break into that business than we were prepared for. You can still see our designs here: http://rumplo.com/people/person/RobitStudios. We were very much into geek culture and trying to design shirts that's made you think a little too. One of our most popular shirts was Joust, based on the classic arcade game.
A couple of months ago I was contacted by Lonnie McDonald, who is a Joust champion. He can run the score of any Joust machine up to 9999999 (the max the machine can show on screen). He wanted to puachase a Joust shirt from me so he could wear them at competitions and events. Since I didn't have anymore in stock I sent him the original design files so he could get them printed up himself.
And he did just that. He rocked the Robit Studios Joust shirt at the Strong Museum of Play in Rochester, NY over the weekend and sent me a couple photos. The fact that a video game champion (not unlike Steve Sanders and Billy Mitchell) would hunt me down for a t-shirt I created moved me so much.
