Articulated Möbius Knot in detail
The story
In 1858 the German mathematicians August Ferdinand Möbius and Johann Benedict Listing each discovered, independently, a strange surface: a strip with one end flipped over before it is joined. It has only one side and one edge. The Möbius strip has become the emblem of topology, and of recycling.
What you'll see move
Set the loop turning: the articulated links run round and come back to their starting point upside down, then the right way up on the next lap. Follow one link with your finger: it covers both "sides" of the strip without ever crossing an edge.
