Tangram is an old Chinese Puzzle, or so the name suggest.
In the late months of 1982 I was trying
to fold something using the lines of
the tangram division of the square
while Thoki Yenn was making drawings
for his 13 Thoki Yenn Orikata.
As you see on the last page of the book,
the paper was standing up
and quoting P.D. James:
“I am an artist, struggling but not tortured.”
