A ball that has a weight attached to one point from the inside would always land on that side, it's the same thing, right?

Correct - we knew we could do that with balls, but can you do it with a pyramid? It initially seems like there would always be at least two stable surfaces for a pyramid, but this group managed to figure out how to do it with only one stable surface.

Last time I checked, spheres are shapes.

But the article references a "pyramid-like shape"

Yeah, but the challenge in this case was to achieve it without any rounded edges.
