It was nice to see the theoretical posting on the V-flex. I like to call flexes, such as the V-flex, in which face numbers, based on the pinch flex, become...
Dear Les, Thanks for your message. I have been asked before, even by Stone, and I have always said yes. However, I don't have a proof. It looks as though the...

HA!!! I did a 30 unit PHiZZ dodecahedron, and that was large enough and stressful enough for me. I haven't even totally read the article, and what I did read...
Hexaflexagons and Tetraflexagons (the kinds composed of squares, not triangles) are all well and good, but it's refreshing to flex something completely new...
Ann Yes, I did discover all the octagon, pentagon, and hexagon flexagons in my book, only to find later that some of them are described in the report by...

Ann's first question is how did I think of compound flexagons. The answer is that the basic idea came from Chapter 13 of Conrad and Hartline. They provide...
Well, the compound flexagons are an incredible achievement. I recommend all "flexers" to venture beyond the variations of the hexaflexagon (wonderful though it...
Thanks for taking the time to build one. The traverse shows the quickest way to see all faces. Your way could be more fun. Going through the traverse means 'do...
Well, I THOUGHT I could do the traverse with my eyes closed... When you do the traverse, do the "subdominate faces" (to borrow a term from music)--the violet,...

Nice flexagon site! I like the fact that you include templates for the often ignored tetrahexaflexagon and the pentahexaflexagon. You might want to check out...
