Septimus blinks and stares before laughing richly, again. This boy, he's decided, is definitely good company. "I have never seen anyone use windcrafting like that," he admits with delight.

He leans a little closer, reaching out with sense even as he just takes a look at it, trying to get the feel for what's going on here. Truthfully, it might not be so different from some of the principles used in flight, if he's gauging it correctly, just contained and hooked into a circle on itself.

"How hard is it to control? And balance on?" Septimus... probably wouldn't do this himself (much), but he's already wishing he could somehow get this back home for the kids to play with.
