Details: I would write more about this GBC, but I'm still spending time studying it. The video quality is a bit lacking, but the modules in this one are spectacular. Lots of brilliant stuff here - pneumatics, Mindstorms, trains (the train is controlled via RCX to stop and start in the right places to load/unload), an all-around great variety of both classic and very original sorts of mechanisms. There are even Spacewarp-style sections with loop-de-loops, a base 5 ball counter, and color-sensitive sorters to tell the basketballs and soccer balls apart. I'm not sure exactly where this layout was setup or how many people participated in constructing it, but I'm suitably impressed with all involved.
