Link Starbureiy's OpenTheorem™-sponsored webnode dedicated to mathematics collaboration.
This project place on Google Code is open for gadget and widget development. Anyone is welcomed to contribute executable and embeddable code for creation of such XML files. The goal is to design gadgets/widgets that can be included in the Google Friend Connect database, and hence, uploaded (embedded) into the FUNode. The vision for such projects is to have fun-themed items and interactive content (e.g., games) that are relevant to human learning. The material here supplements the technical development of the FUNode site.
