Chameleon's Coed Supper Club is an extensive interactive environment that I designed beginning in 1992 on (EVIL!)Mud, a TeenyMud which can be visited by telnetting to evil.xibo.com 4201.
Once you have chosen a nick and password for the MUD, type "@tel #7059"
to teleport to the Club. From there, feel free to explore in any direction!
I especially recommend spending some time in the Alphabet Nexus...if
you can find it.
