I just finished playing with the new open-sourced TourHUD created by the Electric Sheep Company for the GSD&M ad agency. The Tour HUD ("heads up display") is a very easy-to-use tool for creating your own custom tours of various spots in Second Life. There are already two — one for newbie-friendly areas and another of women’s shopping venues.
It took me about an hour to create one focused on my own pet-fascination: real life places simulated in Second Life. Right now the HUD takes you to the Second Life versions of Dublin, Amsterdam, Venice, Hollywood, Egypt, and Rome. IM me in-world (Rik Riel) if you would like one to try out. Or head over to Idea City to get your own.
