At LambdaMOO, homes are classified as ‘objects’ just like everything else, from your own virtual body to the messages you send, and once you have created an object of the variety called ‘room’ it can become anything simply by virtue of the way you name and describe it. The convention is to not just describe the place but to pay attention to the user’s experience in being there. In this way, you can build any places or objects which arise in your imagination, and as many as you like. You can build a series of connected rooms or they can each float untethered in the vast conceptual space of the MOO. But that space is not unlimited. Any MOO runs from a database and that database is of course finite in capacity. To ensure fair sharing of it, users are allotted a quota of kilobytes to cover mail, object-creation, home building and what we might call ‘personal development’ – e.g. one’s various body morphs and other fripperies.
