The most spectacular bit of this one was the double trampoline. The trampolines are already somewhat difficult to aim, so combining the chaos of two trampolines seemed especially dangerous. Indeed, it was the double jump that usually caused balls to leave the system. Still, it was amazing when it worked, and it worked most of the time.

Dave was hoping to do a cube-shaped "tower". Unfortunately, doing a proper cube means there aren't enough places in the middle to attach things. We settled on this double-depth approach, which allowed for lots of complicated track routing without a lot of fast ramps.

This one was intended to push the boundaries of Chaos Tower designs. The original idea was to have the chain going up the center. That was prohibitively difficult without having the chain lift be at an angle. At that point, it seemed more interesting to put the chain at more of an angle.

The Chaos Tower made its first away trip to Bret's house. Bret hadn't seen a working tower until we had this one built, but Dave and I were happy to help take care of that.
