I Think I know...
This is the ride that the seats are placed on either end of the track, on a
seperate axis. At specific times during the ride the seats can spin around a
full 360 degrees, or hang upside down, even though the train is on a flat
peice of track.... (It appears that they are going to do this via a gear
rack? (you know the 1 x 4 LEGO plate with teeth on it) and mesh this with a
gear...
Then again I could be completely wrong...
