A Möbius strip is a two-dimensional topological structure: a three-dimensional figure containing only one side and only one boundary component. A model can easily be created by taking a paper strip and giving it a half-twist, and then joining the ends of the strip together to form a loop. It was discovered independently by the German mathematicians August Ferdinand Möbius and Johann Benedict Listing in 1858.

Inspired by the mobius strip, Stop4Stuff creates "Twin Rail Mobius pendant", a set of nested Möbius strips loaded with ball-bearings.

"A half shell and 3 rails form a bearing-like structure to encapsulate a train of 6mm balls in a mind-warping cage with a twisting, fascinating movement bringing to life the only pendent of its kind in the world.

Includes a 4mm loop for attaching to a necklace or leather cord.

Its a kind of kinetic math art double möbius (mobius or moebius depending how you spell it) band or strip like structure with rails forming a continuous double loop ring track for ball bearings to travel around. I bought some 6mm chrome steel ball bearings and retro-fitted them. Chrome steel balls can be 'blued' by heating with a gas torch, see the video below":
