| The designs are fun, although I find that the thicker paper

| If you find flexagons interesting, you might like trying to find
| a copy of Martin Gardner's "Scientific American Book of
| Mathematical Puzzles and Diversions" at your local used book
| sale. The first chapter is about flexagons and it gets better
| from there! Wonderful car ride, plane, etc. distractions.

| When I was bored in school, I'd make kaleidocycles (a 3d but less
| interesting flexagon) with a sheet of paper, a pencil, a ruler,
| some scissors, and a glue stick. Once I learned Illustrator I
| began to make some custom printed designed ones.
