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.
