This was fun! Reality is boring, isn't it? Take one of the most boring 3d basic objects you can get - the cylinder, here resting on a square cubical base, with light coming from the right.
Look at it in different ways.
What if your eyeball was in the shape of a cube, what would a cylinder look like then? What if you could only see in 4d space, what would a 3d cylinder look like?
What if you turned a cylinder inside-out, and what is its most basic form if you look at it in a non-euclidean space?
Everybody knows what regular geometry looks like. Create a new geometry! Then put the cylinder into it, and see what it looks like.
