Today the New Media Consortium (NMC) announced a $250,000 two-year collaboration with Sun Microsystems to launch the Open Virtual Worlds Project, an effort that is aimed at making it easier to learn, work, and exchange ideas in virtual space. The project will develop a range of standards-based, portable open-source educational spaces, content, and objects, and use them to extend Sun Microsystems’s open source Project Darkstar and Project Wonderland virtual world platforms.
