I have just completed David Brill's wedge flexicube and posted pictures on my site www.raviapte.com/gallery/BrillFlexiCube This is an origami model designed by...
... Since this is a flexagon group its worth noting that this flexible structure isn't a flexagon as such. Fexagons are flexing strings of polygons. On the ...
... Well ... definitely ... maybe! As far as I can see the term flexahedron is in use in three quite separate ways. There may be more. Yes ... it is sometimes...
... The first two seem similar enough to me that flexihedron can apply to both. The last, since it flexes in the fourth dimension should be called a...
Douglas Engel calls them flexadrons, and Doris Schattschneider calls decorated rotating rings of polyhedra kaleidocycles. Les ... From: "Dave Mitchell"...
... There were rotating rings made of tetrahedra that Martin Gardner described in his Scientific American column back in the 1950s when I was in college. I...
... I wrote a program to generate kaleidocycles recently. Here is an animation based on one (740k) http://www.freewebtown.com/adrian/misc/kc_tet_03.gif Adrian ...
... I googled flexadrons ... and got no results! I have however discovered that Douglas Engel also used the term flexahedron to refer to rings of polyhedra...
... That is certainly a nice animation. If you want the framework, a ring in the center of each face runs out to three rings perpendicular to the center ring...
Hi Dan ... There is a nice page with instructions here http://www.mathematische-basteleien.de/kaleidocycles.htm (or search on 'kaleidocycle' for more) Adrian. ...
I just sent the link to my nephew at the Uof I, where he works in the library. So far, he had been good at tracking down obscure articles. I'll keep you...
The page you found is the table of contents of Les Pook's book, "Flexagons Inside Out." And on the rotating rings of polyhedra, Peter Hilton and Jean...
... If anyone wants to make an animation, the kaleidocycle program is not yet finished but works fine for regular tetrahedra. It is undocumented but included...
Hi John ... It is just a basic Python script to output the model stages of a single chain in OFF format, and another script to control the animation (using the...
... I'm familiar with these from my use of Paint Shop Pro version 9, where I use scripts to draw geometric things. When I looked at the websites I saw...
Hello All My web site is now live. It contains some information on flexagons, including a recently discovered decagon flexagon with 7 faces. The URL is...
Hi All ... The program is now working for general polyhedra. The example animations in the following two messages have stages of self-intersection, but may be...
Recommend that everyone visit the sites listed in the last two messages. Les, nice to see more on the lesser known flexagons, like the pentagon flexagons....
Wishing all flexagon lovers a healthy and happy 2007--and one that includes lots of creative folding. This group now has 72 members--pretty good for such a...
Everyone knows that the nonahexaflexagon has 15 mathematical faces when restricted to the pinch flex. The construction and the Tuckerman traverse for the...
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...
