SX T-Shirt Cannon

[cardinals08]

I went to the Supercross in St. Louis today. When we went down into the pits I saw a kind of golf cart vehicle and mounted on the top was a cannon. Its chamber was painted orange, and had the word "Kicker" on the side, and the barrel was black. The valve (I believe it was a Supah) was also orange. This cannon was used to launch T-Shirts into the crowd later on. This looked to be a really nice cannon and was wondering if anyone knew who built it.
