This is a model from last month's exploration. Four circles in a tetrahedron patten designed to a truncated form.



This month I added another of the same system with some variation in the forming.


m-2   m-3


In going back to exploring the possibilities in reforming the tetrahedron net the helix form continues to hold my interest as does my amusement in using my business cards.



m-5    m-6

m-7   m-8



Three more units were attached to the three solid faces of one side making a partial bi-pyramid. This is the seed unit for systematically adding a helix unit from single circles. They were attached only where there was a congruent face and they did not interfere with others that were added.







m-11   m-12 



Below I started exploring further various helix formations using variations of the reformed tetrahedron units used in the above system.



I had to make this from paper plates to look at the difference. When the open space are larger you see it differently making connections otherwise not seen.


...like this one using four circles and each unit of three tetrahedra opened in a different way.



Below is a hinged tetrahedrahelix with 2/3 or the circumference folded out on each unit of two circles joined into a tetrahedron. On the left the helix is to an open twisting and on the right is reversed into a tighter twisting. 

m-21  m-22


Here is another reformation of the same helix system.                            



Below is another hinged joined helix that has very little opening movement but lots of individual isolated movement with each unit making a jiggling movement rather than twisting.
