Movies of secondlife In secondlife.
attached is an image from the cavern theater at legith's island park, showing the boat ride around the park.
I wonder if movies of second life embedded in second-life will become common. In particular at second-life classes.
Since the movie by default includes the UI this could make it easy to show people how to build and perhaps evens script. (however if you are making a movie of scripting more editing might be better than directly recording you SL window)
The instructor could explain and show how to do something, then ask the students if they have questions, and allow the to practice.
This idea could also be used for some in game movies, but I know some people where already thinking about that, or something like it.
btw if you want to watch the boat ride either stop by Legith's Island Lighthouse in lozi, or play the actual video:
