Theme Park Discussion / Interesting Coaster Design

Was stumbling about on YouTube looking at homemade coasters and found this pretty good looking video of an interesting design of a roller coaster. It's only designed by a student at Coventry University, so I don't this will appear in the world soon, but again, it'd be awesome to ride.

I wonder if something similar to this would be feasible in any RCT.

NOTE: Some of the physics look at bit off, but still, cool concept.

Anyone find something interesting (relating to coasters) on the net these days?

I think that design is a bit pointless. You can get the same movements with normal trains too... I even think you won't notice the dropping seats if you're not on the lifthill.

Beautiful animation btw.
