Open Wonderland is a 100% Java open source toolkit for creating collaborative 3D virtual worlds. Within those worlds, users can communicate with high-fidelity, immersive audio, share live desktop applications, and collaborate in an education, business, or government context. Wonderland is completely extensible; developers and graphic artists can extend its functionality to create entirely new worlds and add new features to existing worlds.
One important goal of the project is for the environment to be completely extensible. Developers and graphic artists can extend the functionality to create entire new worlds, new features in existing worlds, or new behaviors for objects and avatars. The art path for Wonderland is also open.
