How to Get to the Center of a Room?

Caleb steps forward into the center of this platform and begins to just think up. He's levitated? Yeah. Come on, come on, don't be shy. There's much to see. It's like Hogwarts for the first day. I'll try and go up and spin as I'm going. Any happy little thoughts? You watch as you slowly begin to corkscrew up. And above those sliding doors are little, almost like a wooden aqueduct built into the walls. Little tracks moving around the room, some diagonal, some straight.
