I'm building Reverchon's "spinning raft" ride. It's a transportable river rapids fair ride. It had been made by the French and the Italian (Fabbri) but the original (park version) idea is in hands of Intamin. They designed the ride for the Dutch amusement park De Efteling back in '79. The lego model won't really look like the spinning raft ride. More like 'a' spinning raft ride. I don't have motors, so it will never be able to work without a human hand, but I will try to make it look as good as possible with the parts I've got. I don't really have many bricks, (appr. 10k) but I hope it's enough for the complete ride. I'm building some parts first on my computer, (like the boats) because I have pretty much every brick indexed in my peeron account, so that I can see wether I can make it IRL. It will take much time, so I hope you can wait :p
