Flexagon links
"Flexagons" are far more than the flexible hexagons that gave them their name.
Popularized by Martin Gardiner in the 1950's, they are still fascinating yet
easily-constructed paper objects with still incompletely-plumbed mathematical properties.
If you have lots of time, grab some paper, glue, scissors and crayons
and follow these links:

or Magnus Ennarson's Flexagon page
- David King's Flexagons pages include
a 3-D simulation of a flexagon flexing
