These “Buckeyball” magnets look like fun (but IMO a tad pricey for a good-sized collection). The towers are just for structural integrity; it’s the ones on the battery itself that are responsible for the motor action.

My school’s bookstore has been selling these for a while, but I keep passing on buying a set. There are also Buckycubes, though I just imagine they’d be more of a hassle. In any case, fun video. I may have to finally throw caution to the wind and get a set some time soon.
