Kokichi Sugihara's Impossible Objects - Yazata - Oct 13, 2022
Objects which transform topologically when rotated or seen through a mirror
Or at least seem to. It's all optical illusion where what seems to appear is physically impossible. It's based on the principle that many different 3-D shapes can create the same 2-D image, such as what's seen in a mirror, a video image, or even the image on our retinas.
Sugihara's rather elementary discussion of their properties and how to construct them
