I'm still geeking out over how this **** ball works.

You've been able to buy radio controlled balls for years, I wanted one when I was a kid, and that was in the 70's. And I dare guess that there is some magnetic magic going on keeping it's head on it's body. It is darn cool that they made it practical, rather than cg. Major props to the production for doing that.
