The OpenSimulator Project is a BSD Licensed Virtual Worlds Server which can be used for creating and deploying 3D Virtual Environments. It has been developed by several developers. Out of the box, the OpenSimulator can be used to create a Second Life(tm) like environment, able to run in a standalone mode or connected to other OpenSimulator instances through built in grid technology. It can also easily be extended to produce more specialized 3D interactive applications. Check out the list of growing features to get an idea of what OpenSimulator is capable of.
