The Virtual Math Teams (VMT) Project (vmt.mathforum.org) at the Math Forum enables K-12 math collaborative learning, professional development of educators, & group cognition research. VMT is now integrated with GeoGebra (http://www.geogebra.org/).
A fair attempt at the Keplerian tradition to explore the solar system
...Apparently his observance of a harmonic law of planetary motion was reason for him to propose a computable system of pitch and harmony deriving from angular velocity.
The purpose of the programming project is as a tool to examine his system. With Java 2, it provides an open-source solution for listening to harmonies so generated by planetary motion. This program can run on any computer provided with a JavaVirtual Machine (Rev 1.5 or greater).
JAVA 2, system independent. Purpose:to encourage research in harmony in astronomy, math and music. ...
The Wolfram Machine project is an effort to create a set of documentation and useful modules (both hardware and software) for a computing architecture based on the mathematical theories presented in Steven Wolfram's book _A_New_Kind_of_Science_.
