Team 2403
2008: Rusty (because absolutely everything except the kit frame was made of steel, the judges absolutely LOVED that!

)
2009: PEZZ (the balls were stored vertically and shot out one at a time, and the whole thing was a rectangular prism. Named after the candy, but with another z to avoid copyright issues)
2010: Still undecided! perhaps 'Patar' because our resident welder, Patrick, did an AMAZING job making custom parts this year!
