How about a giant funnel, like those things that marbles spiral down? (line the rim with chimes and keep the lazy suzan in the center) The gamepieces would be those little blue racquetballs that team 128 was handing out at nationals. Near the base of the chimes there'd be a shield to hold the balls in and keep them from bouncing all over the place; instead letting them roll down the funnel (maybe in a spiral). The goal would be to throw the balls up and hit the chimes (more points for certain interval sequences). Getting hit by your opponents balls (when they're on the ground) would give them points. Firing balls at an opponent would be penalized. As your balls are rolling down the funnel, you should try to pick them up. The "spout" of the funnel is just a recession that makes it more of a pain to collect balls (encouraging teamwork). Since this might require a ceiling, there could be a giant gong (suspended horizontally) in the middle of the ceiling, where you get special points if you hit it. You are also awarded those points if you fire some balls on top of the gong, and someone else knocks them off by firing at the gong.

Now what could Autonomous be? (thus the problem)
