http://www.NoLimitsDevCenter.net/p5672 This is a fairly old project that I had going for the CS contest right before the site closed down. Since the contest never finished I forgot about the coaster and moved on to other stuff.
EDIT: Right, well I couldn't figure out how to support the tower properly so I had a go at my first 3D object. I think it turned out fairly well and I thought it might work for supporting the ride. I'm going to remake it with fewer windows but this is just to see if it would be alright. What do you think?
