As it is the tradition in LudumDare, here is the Timelapse of my game.
I’ve used my own script (for MacOSX) to capture the screen each 10 seconds, and then fed the images to ffmpeg to generate the video. If you are interested by the scripts: https://gist.github.com/gre/11219793
I also used Google Gangout in the whole session, as a way to put my webcam in the timelapse, but more importantly to have other LudumDare friends coming in it As you can see @mrspeaker appeared a few time in the timelapse showing me the advancement of his crazy Metal Meter game (well next time we may try to be on the hangout longer). 2 LudumDares ago, we experimented working our entry the whole saturday in a Paris Starbucks, this was a bit crazy with all the tourists.
I think this Hangout approach is a nice alternative to the classical Twitch stream. It is much more powerful actually because you could easily stream a Hangout back to Youtube, and Google Hangout is so easy to use from a computer or a phone!
