pic: Three Trackballs?

Thanks Phyrxes. Gosh, no wonder I couldn't find it -- wrong thread name, wrong poster. It's a wonder I can find my way out of bed in the morning...

Looking at those photos again I wonder why they even have those upper panels. The bottom ones I could see, if only for sonar and to match the outside walls. Come to think of it, the outside outside "protector" walls (if you follow me) don't have the panels. Wouldn't it be easier to make a rule "no robots can go thru the wall"? Well, it makes for good post-season rule changes.
