Here is an interesting mod from Lost_Jedi. This will allow you to finally get off your "Duff" and take a Walkabout tour of your Bridge set. You can control the movements with the [i]" N, B, and
Shift + N "[/i] keys, using your Mouse to control your direction. However, this will not work on the Galaxy Bridge set. This an interesting mod, and I hope to see more work from the Author(s) in the future. Definitely worth having a look at. . .
