- Come to Valhalla
- Valhalla is—or was—a MOO. MOO is a ‘programming language’ for creating multi-user dungeons (MUD). MOO is object oriented (thus, MUD, Object Oriented). MOO was created by Pavel Curtis and Xerox PARC, who are to be commended for their work. While MOO is ancient technology, there are still people who find it fun and useful.
