I've recently finished recording a small video showcase of the UH virtual campus I created inside Second Life. I completed the development a few years ago but, happily, it still sees use. I've used the same location to host meetings related to projects funded by the European Commission (exploring the affordances provided by virtual spaces) and for teaching undergraduate students the fundamentals of cyberculture and aesthetics.
I'm posting it here for the sake of posterity more than anything else. The only record people are able to have of their work inside Second Life is via this sort of documentation. Since all data is stored on Second Life's server cluster, it's impossible to export your creations.
