The device in link 2 appears to be completely different from the ones in links 1 and 3. Possibly a fixed sphere instead of a virtual one?

Oh, wait. Also a virtual sphere. The video didn't show it not rotating, but there are other photos of it not in motion, so you can see how it is constructed physically. Unlike the other two, the LEDs are visible from the inside as well as the outside.

I'm curious how power gets to the LEDs, and how it gets sorted out. Can all 32 be lit at a given instant, or just one?
