Years ago we did a 15 second animation for Nokia Shorts – and really enjoyed the challenge of trying to make it as much of a complete story as possible despite the tiny space. Since then, periodically, the idea of animating our cartoon strips has come up at the Guardian, but somehow we've never cracked it (ie got off our arses and done it). For one, we weren't always sure we knew how to make the animations do something the still images didn't already manage. Just trying to replicate the gag in a moving form can actually spoil the way, in a still, the viewer can create their own sense of timing, their own path through it. When the Guardian came to us and wanted to try something that just went out of social media, it seemed like the right space and opportunity to give it a go.
