Open Simulator, Singularity and METAbolt

Where to download OpenSim. I think Open Simulator is the way of the future, or at least I did when I could actually run it on my system from source. I wish I had that old version somewhere.

Open Simulator [Main Page]

OpenSimulator is a Second Life like simulator that is open source.

I prefer the Singularity Client. I also like the METAbolt text based interface. I figure they are the MUDs of the future, so I figure I should make use of them and learn what is already there. I also like CoffeeMUD, a Java based MUD simulator. You can run it here.
