If
you want to make this puzzle, you need a plate with a thickness of at least
1,5 cm. The dimension of every piece is 5x9x1 units. Cut the pieces with a
jigsaw according to the diagram below. It would be very beautiful to make
this puzzle out of two different kinds of material to get the black-white
figure as in the picture above. (Ebony and ivory would be very suiteble for
this puzzle, but working with those materials is, for as far as I know, also
illegal)
