For those interested in flexagons made from squares, I was just sent a scan of a ~1970 article from the journal, Nauka i Zhizn (Science and Life, Russian:...
I cannot read Russian, but these diagrams are fairly good in the article. Notice that there are dots by the numbers placed in different corners. These dots...
I made it as follows. Make the net as shown in the sketches (Fig 1), with the cross slit in the centre. Enter the numbers on the left hand sketch. Turn the net...
These directions work great! I was able to make the flexagon in just a few minutes by cutting between the 2 and 6 first. I also folded another one without...
I am writing a new book on flexagons, and have an agreement with Springer for its publication in their 'Solid Mechanics and its Applications' series. A brief...
Cool, I was wondering how your latest book was coming along. Can you give us any estimates on when it will be out? Looking forward to it. Scott Sherman ... ...
Timescales are vague at present. I hope that it will be out early next year Les Pook ... you give us any estimates on when it will be out? Looking forward to ...
Great! I look forward to seeing this new book. I will be happy to advertise on flexagon.net when it is getting close to publication. 100 nets will keep us...
Hello, I have had this flexagon for several years. When assembled, is not flat, ever. When looked at on edge it can look like a bow tie. When flexed, there...
This is one of the rotating rings of tetrahedra that Doris Schattschneider calls 'kaleidocycles'. I don't know the source of your example but there are...
Hi Kathy, What you've got there is called a kaleidocycle, which is a ring of tetrahedra rather than a collection of triangles. And it looks like you found...
Hello, please visit my page http://www.mathematische-basteleien.de/kaleidocycles.htm. Greetings from Germany Jürgen ... Hello, please visit my page ...
Hi Kathy ... It looks like a kaleidocycle http://www1.ttcn.ne.jp/~a-nishi/kaleidocycle/z_ani_kaleido.html This page might give you some more ideas for the...
THANKS to all who answered. As soon as I read the first one with the name Kaleidocycle, a light went off in some dark recess of my brain. I have just spent...
Attached is a file describing a Hooke's joint flexagon. The file has also been uploaded to the Member's Section of the website. The Hooke's joint flexagon is...
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...
