A moo is a text object oriented virtual reality environment
which was originally created for teaching people over the net.
Later, the people of LambdaMoo took the source code and improved it,
making it into an almost full VR environment.
This moo would be based on the LambdaMoo source code, and would try to improve it to a full fun virtual reality environment, and not necessarily a text one. And of course it would be a more playable version for those of us who like RPG like games.
