Couple of theming concepts before I forget them...

The first is for a turtle themed Zamperla Disk-O. I wonder if it's possible to put some kind of tunnel around part of them? It would have to have a huge envelope to allow the wide spinning car through without risk. I wanna explore this one more because I think there's lots of visual possibilities like tiki, reefs, beaches, huts, etc.

the lower one is that derelict themed self representational wooden coaster I keep going back to but am terrified of working on.
