A bit of flexagon theory
This is a rather rough and ready approach to how flexagons work. I've read the paper by Oakley and Wisner (1957) and to be honest it uses too much jargon for me to understand.
It was basically easier to work out for myself most of what follows. Please excuse my hand-drawn sketches, but this is only an interest for me, and I've lots of other things to do.. ;). I've recently expanded the page, after a couple of people contacted me with ideas, but there's still more work to do. Nevertheless, it's a good start....
I guess many people reading this will be connecting via a modem and telephone line, and you'll no doubt want to read this stuff offline. Because there are a load of gif pictures as well as text, to make things easier I've made a zipped up file of theory discussion and gif pictures.

To save me updating the archive too often, I'm putting the latest developments and thoughts on the theory on a separate page. To see them, click *****here*****
Any feedback will be greeted with interest and courtesy. About one in fifteen visitors to my flexagon site make it to the theory, so consider yourself one of the select and intelligent few. That means you might be able to help me out. I've had some excellent, enjoyable and helpful discussions with clever people reading this stuff; do join them....
