WHY ORIKATA ?
Knowing only too well. that to claim to be the
inventor/creator/discoverer of a special design can rightfully
be challenged by anyone, who has discovered/created/invented
the same design, I have chosen to call my editions of these
shapes in this booklet by the Japanese term ORIKATA, which
according to the A.B.C. of ORIGAMI by Eric Kenneway is:
I) An archaic Japanese term (lit. 'fold shape) which has
the same meaning as 'origami'. (folded paper)
2) A modern Japanese term, written differently from 1),
meaning 'how to fold' or 'folding method'.
(B.O.S. magazine No. 96. October 1982, page 30.)
I use the term in the sense of 'my way of folding these shapes'.
I have 'lifted' certain of the ideas in this booklet.
The method of trisection is the Fujimoto method.
The DISPLACED HALF CUBES and their ring is lifted from
MODELLI DI GEOMETRIA ROTATORIA by GIORGIO SCARPA.
This very Interesting book was given to me by Roberto Morassi.
The Origami version is my own.
In SCIENTIFIC AMIERICAN from some years ago I found in
an article by Martin Gardner, that the Chinese had lifted one
of my ideas many hundreds of years before I was born; namely
splitting the cube into 3 SKEW PYRAMIDS and calling them
Yangmas, the same article also shows that six Pyramids will
fold respectively into a cube and a rhombic dodecahedron when
taped into a cross of pyramids.
I have not invented the square or the cube or
the tetrahedron, neither have I invented or created the rectangle
nor the wrong tangle.
It was all there before I came along.
