I like the idea of the twister concept.
The twister concept looks mostly stationary... it might be more interesting if it was more like the Sky Roller, but wrapped with a toroidal projection system and some rider control over the pitch and altitude.
My fantasy plane ride would be something like combining the Eyerly Acroplane with the Sky Roller... as in, put multiple forks on a spinner and lose the propeller.
BTW, footage of the Acroplane! (00:58s in)
