psst... wanna know what I've been spending some of my evenings doing? Here's a film shot in Second Life documenting the club I've been working at. It's set to Tom Waits! As far as the work-safe factor... it depends. There's no nudity technically, but it's full of scantily clad dancers, so you be the judge.
My avatar appears briefly at the beginning; I'm the brunette in the peacock feathers!
