This gigantic collection of pieces for a marble rollercoaster construction set was a hit at Penguicon 2.0 and will be back in 2005! We have an assortment of catch baskets, tubes, joints, drops, trampolines, loop-the-loops, sound makers and vortexes for the ball bearings to interact with, as they careen through the tracks that you can design throughout the weekend. It is supposed to be possible for logic gates to be constructed with a Chaos Toy, but so far this has never been acheived.
