DEMOS with POSITIVE IMPACT references and includes software on a variety of platforms including,
GEOMETER'S SKETCH PAD
Not all demos include routines for each of these platforms. Often submissions included some implementation of the demo on one platform. When possible we tried to develop an alternative implementation on another platform. In some cases we developed accompanying software to compliment demos for which none was included. Many times our developments were used to generate animations that are included with many demos. See also Animations and JAVA.
