             Deskcal | The World of Geometric Toy
             Tapped In - ENC Math and Science Fair


                           DESKCAL

       http://www.ces.clemson.edu/~rsimms/neat/deskcal/

  Just in case you do not have your desk calendar yet or if
  you would like to add to your collection, Robert Simms' site
  has a great solution. Since a year has twelve months and a
  dodecahedron has twelve faces, Simms' Deskcal combines the
  two in a calendar that folds up into a dodecahedron.

  Also available are:

   - calendars to fold up in the shapes of the four other
       Platonic solids
   - calendars in other languages
   - the Chinese zodiac to fold up as a dodecahedron

  Play with animations and applets of Buckminster Fuller's
  Tensegrity and the Indian Ball (also known as the
  flexi-sphere), as well as wire-frame renderings of the torus,

  other objects. Nishihira also provides instructions for
  building paper models of origami springs and spinning pop-up
  cards.
