In spring of 2007 I designed a bunch of logo / theme video loops for Nitro 3: Zero Gravity, as well as created three countdown videos to kickoff each session.
The theme "Zero Gravity" was focused on astronauts and space travel. One side of the stage had a rocket, while our video mixing and tech area was on the other side - dressed up to resemble a NASA control room. It was the only event I've been a part of where I was on stage the whole time (not a big fan :)
Using footage shot by myself and others during the event, I edited a recap video to be shown the morning after the conference wrapped. I also provided a better edit of the event a couple weeks later to help promote future events.
