That's an intriguing hinge. Once you figure out how to make it, the model works quite nicely. I immediately started thinking about interesting patterns and...
I don't think it's possible to construct Hooke's joint flexagons that will traverse more than one cycle. The reason is that from a mechanical engineeering...
I just watched most of a commercial from Target (I missed the beginning). The images were unfolded as if from the 8cube flexagon (whose name I don't recall)....
Awhile back I posted descriptions and pictures of some of the flexes you can perform on different versions of the triangle dodecaflexagon. I finally got...
Nice videos! These videos really helped me see how each of these flexes work and especially the flow that Scott has created for each of the flexes. I was...
... flexes you can perform on different versions of the triangle dodecaflexagon. I finally got around to posting videos, which give you a much better feel for...
Thank you Scott for your post. I have sent it to everyone that I know. The details on our site are a little sketchy, but we would like to announce that we have...
Interesting results, Bruce. It's impressive how many extra combinations there are when you add in the v-flex. Is your technique specifically for the 3n...
Yes. A flexagon with 12 triangles per face has been called a dodecaflexagon or 12-gon. And when it has 6 sides, it's a hexa-dodecaflexagon. (I think a lot...
As you know regular flexagons of order 3n are made from straight strips of paper that contain 9n triangles. When my students helped me count the one of order...
Scott, these are really fantastic as is your site and the new flexagons on your site. A flex you call the pinch pivot looks like what Pedersen and Hilton call...
Thanks Ann. I think I'm going to have to get that Pedersen and Hilton book - you've mentioned several interesting items from it. What type of flexagon does...
I've posted a video of some of the flexes you can perform on a hexaflexagon at http://www.youtube.com/watch?v=tGQ_I4_N3sE. I picked a 5-sided hexaflexagon...
On BUILD YOUR OWN POLYHEDRA: Some other members of this user group have reported that the book is very hard to find now; I think it is out of print. I did,...
I posted a hexaflexagon with face patterns from Sangaku Japanese Temple Geometry problems. You can find this on the right column of the www.flexagon.,net home...
Fascinating video! When I first read about the v-flex and tried to figure it out from text descriptions found on the Internet, I almost gave up. Scot's video...
Ann I've ordered a copy of 'Homage to a Pied Puzzler' and look forward to reading your chapter, and seeing how your analysis compares with some of my findings....
... I am trying to construct the five-faced braided hexaflexagon but am having some trouble understanding the diagram. Part of the difficulty is that some of...
Ah, it looks like I forgot to mention on that page that you'll get a large version of the strip if you click on the small picture. The numbers should be very...
Yes, it's surprising how complex even simple paper folding is. In one of Martin Gardner's columns, he discussed postage stamp folding. Start with a line of n...
Hello all! I've been trying to create a Tetra Tetraflexagon model in excel so I can use it in my technology class with 1st grades, but I haven't succeeded....
Ann Schwartz had talked about being able to view one face six different ways on the nonahexaflexagon. We have decided to use the dodecahexaflexagon as a ...
It's also interesting to note that the simplest hexaflexagon that shows this behavior is the 7-sided braid - http://www.loki3.com/flex/braids.html. In a...
Scott Sherman has, rightly, pointed out in Posting 512 that point flexagons are not particularly photogenic. This can be remedied by using a different method...
That definitely helps. Giving thickness to the faces, making them a solid color and having holes in the faces all help make the structure more visible. And...
