Help us imagine how an email message travels around the world. Take a look at the collaborative video we started, and then film what happens next. Post your clip as a response to this one. We’ll edit a selection of submissions together to make a final video, which will be featured on the Gmail homepage and seen by users worldwide.Respond to this video with your own clip by August 13, 2007 to be considered to the final collaborative video. All it takes is a video camera, the Gmail M-velope , and some creativity. Learn more about the project at http://mail.google.com/mvideo
