A Klein Bottle -

“In topology, a branch of mathematics, the Klein bottle is an example of a non-orientable surface; it is a two-dimensional manifold against which a system for determining a normal vector cannot be consistently defined. Informally, it is a one-sided surface which, if traveled upon, could be followed back to the point of origin while flipping the traveler upside down.” - Klein bottle, Wikipedia

I was inspired by this incredible shape (object? one sided surface? vessel for magic potions? tool for confusing ants?) If you hold it to your ear, can you hear other dimensions? I am no mathematician and have no answers

This is my attempt at a 4-stemmed Klein-bottle, modeled in Blender - hope you enjoy!
