|This skew Tetrahedron below is 1/6 part of a cube, in the booklet
"13 Thoki Yenn ORIKATA" it is shown as folded from half
a square, but I the great and Glorious Kalmon who is looking after
the welfare of this old guy convinced him that he should use all
the strips he had left over after having made squares out of A4
sheets of paper. The construction of the crease pattern will give
you the format of the paper, that is how much to snip off at the
end. You see Thok being sort of "scissor-frenic" has no
fear of scissors. The crease lines are shown on the special Thoki
Yenn currency where you will
please note the monetary unit is ideas, and the notes are legal
tender in the beautiful land of make believe.
You can use these skew tetrahedra to build cubes.Print out
a whole stack and take 6 and make a CUBE, three left oriented
and three right oriented. Make a PYRAMID with 8, 4 left and 4
Take 12, six of each 'political' orientation, tape them together
in a ring, Yes I wrote tape - sacrilege - alternating between
left and right and it will flex in many funny shapes.
If you make a box that fits this shape and give it
to a friend to play with, he might have difficulties in getting
it back in the box again, because it can flex into many different
forms, but the one that fits the box is not easily found.
