The 1st Gif below were generated with a camera modified to take photos at arbitary intervals using a tilt switch in place of the trigger button. The camera was carried around hung over various peoples necks throughout the first day. The 2nd Gif is from the second day as the heavens opened and hackers continued building and debugging until 5am!
