Now, you can make these any size you want, but I am going to assume
that you will want to make one of these from a regular sheet of paper.
You need to easily divide a strip into 6 equal pieces, so something like
4 cm or 1 1/2 inches would be good lengths. I will make mine 1 ½
inches, so trim the paper to 9 inches. Along one edge, mark off six

This video is based on, and in honor of, Martin Gardner's first Mathematical Games column from 1956, "Hexaflexagons," which can be found here: http://maa.org/pubs/focus/Gardner_Hexaflexagons12_1956.pdf
I remember reading about Flexigons in SciAm while in Jr. High School. And colored the faces, concealed messages, etc. The mma.org link is interesting as Bryant Tuckerman, Richard Feynman, and John Tukey are mentioned on page 3 as some who worked with flexigons.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
