31 January 2005 Vol. 10, No. 5 THE MATH FORUM @ DREXEL INTERNET NEWS 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 Visit Simms' Neat Math page: http://www.ces.clemson.edu/~rsimms/neat/math/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- THE WORLD OF GEOMETRIC TOY - Akira Nishihara http://www1.ttcn.ne.jp/~a-nishi/index.html 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, the magic ring, the toroflux, the reversible polyhedron, and other objects. Nishihira also provides instructions for building paper models of origami springs and spinning pop-up cards. Sections of the site include: - Geometric Toy - Polyhedral Toy - Java Applet -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- TAPPED IN - ENC MATH AND SCIENCE FAIR http://www.tappedin.org Gail Hoskins invites you to join her at Tapped In on Tuesday, March 1, from 7 - 9 PM EST for an ENC Math and Science Fair.
