Here is a link to a video that we created to promote our Second Life Campus.

Notice that we used machinima to create the video. Machinima is exciting in and of itself. It's obviously effective for the promotion of games and virtual environments but even beyond this, it has become a serious media for producing films and other rich artistic pieces. Just think of what we could do by adding machinima elements to our simulations that are delivered in flash. Just one more way to engage learners.
