Here we have stills, the film plus a making_of video:

The winged critter theme doesnit end there though. Massive Black have spun together a fascinating little world using Unity 3.5 where you are a moth and can control a 'body'. The result is a confusing little realtime level you can download to play which has plenty of little flaws but is still a pretty groovy thing - here is Mothhead:
While neither of these projects are particularly relevant to my Moths v Butterflies work, esp now that I am keen to do a board game with the world at present. That said, I did enjoy using Unity for my Cartographer project and it still has merit. In a real-time world I would want my butterfly or moth avatars to fly much more smoothly than we see here in Mothhead, it doesn't feel natural here, the world is very cool, but the controls awkward.
