OpenSim Worlds

OpenSim Worlds is a self-serve clearinghouse for OpenSim OAR files. It is currently home to ten OARs, including the Apollo 11 Moon Experience, the CSI Virtual World and the Mars Simulator from Greenbush Labs.

OpenSim Worlds is also home to a Faerie Castle, from Jessica Random, which is a good-sized OAR file. It has castle on an island with a hidden cave under the castle and waterfall behind, and plenty of trees and mushroom groves.
