Did you have many problems with trackballs getting launched off of, or falling off of, the sides of the float? That just seems to me like it could cause a precarious "trackball of doom" sort of scenario in a crowd

(actually, might be sort of funny to see(assuming that no one got injured). Reenactment of an Indiana Jones scene at a parade=Awesome

)
Regardless, that's really cool. You guys only won third place? I'm surprised. I personally would have loved to have been there to see it.
