As a minor thing of note, readers interested in the Science of Automatic Vehicles might also be interested in visiting the Third Year Anniversary Celebrations, as detailed on the Second Life Wiki. The monorail that you may travel upon there works upon a similar system to the Caledon Tram, which is not terribly surprising, as I scripted it. The actual car itself was not by me, but by Merle Widget, and the fabulous monorail stations and track are by Lethe Naumova. (The overall style, if there is one, of the Third Year Anniversary Celebrations, or "Three Yak" as I have taken to calling them, I consider to be somewhat "retro" but of a later period - what I term "Gernsback" - than my more usual one. I would say, '30s to '50s.)
As with the Tram, one can watch the progress of the monorail and travel directly to it by visiting the Monorail Status Page, and also laugh when it decides to misbehave (which as yet it has failed to do, though I expect it will today after our Regularly Scheduled Down Time). Be warned, if you decide to teleport to its location, that it is somewhat high in the air.
I do very much advise any reader to visit this Exhibition, even if they despise trams and monorails, as there really are some exceptionally impressive creations to be found there just on a brief wander - not to mention the events that will be taking place. An extensive timetable of the latter can be seen in this entry by Mr Hamlet Au.
