The Vortex Tunnel.
Who knew.
This is possibly the coolest thing in the whole world.
I went to a Haunted House last night (Old Bloodworth Manor).
After some twisty maze stuff, and a mad scientist, I was ushered into this area by either a small child or a dwarf. I'm not sure which.
And then ... wow. Just wow.
It was like being in that episode of The Six Million Dollar Man, the one with Andre the Giant as Bigfoot.
After going through the haunt once, I was able to go back and play with the tunnel. A lot. Like for twenty minutes, playing with the visual/spatial effects. Leaning toward the direction of rotation is more disorienting than away from it, and if you pick a fixed point straight ahead of you, the sensation of movement is even more disorienting.
I have great kinesthetic sense, and was unable to walk a straight line through it.
