What is RHOMBO?

   RHOMBO blocks come in two basic
         shapes each is a simple rhombahedron
             (a stretched cube).

  Every face of a RHOMBO block is a
     special Rhombus
       (a parallelogram with
           equal sides).

       The lengths of the two diagonals
           are in the mystical Golden Ratio.


The Golden Ratio was the basis for the design of the Parthenon in ancient Greece.
