Arriving at the central metaphor was as team effort - I remember Simon Davies, Paul Turner, Lou Lauwersy, Dawn Butler, Daniel Gill were all around the table with Dave Low and me. Then Dave and I collaborated on the storyboard, and he did the hand drawn animation and selected the soundtrack. The yellow frame was a response to the client's inflexible brand requirements but somehow I think Dave made it work.
Looking back, one of the things we're most proud of is how much play this little movie has received. We released it in early 2009 and it's still alive in the client's arsenal!
