LambdaMOO gained some notoriety when Julian Dibbell wrote a book called My Tiny Life describing his experiences there.
[3] LambdaMOO has its roots in the 1978–1980 work by Roy Trubshaw and Richard Bartle to create and expand the concept of Multi-User Dungeon (MUD) – virtual communities.
The coat closet opens onto the center of the house in The Living Room, a common hangout and place for conversation;[6] its fixtures include a fireplace (where things can be roasted), The Living Room Couch (which periodically causes players' objects to 'fall through' to underneath the couch), and a pet Cockatoo who repeats overheard phrases (which is sometimes found with its beak gagged).
To the east of the entry hall, hallways provide access to some individual rooms, the Linen Closet, and to the eastern wing of the house.
In the eastern wing can be found the Library of online books, the Museum of generic objects (which account-holders may create instances of), and an extensive area for the LambdaMOO RPG.
Since the creation of the original LambdaMOO map, many users have expanded the MOO by making additional rooms with the command "@dig."
A petition may be created by anyone eligible to participate in politics (those who have maintained accounts at the MOO for at least 30 days), can be signed by other players, and may then be submitted for administrative 'vetting'.
