Stuck in traffic circling London, art materials safely packed out of sight, darkness falling and the dawning realisation we will not be catching our reserved place on the cross Channel shuttle.
So I have to play at drawing with a slow shutter photo app which has infinite possibilities and naturally very little chance of failure because car lights on slow shutter speeds are always going to work. I probably could have done these blind.
But then I became fascinated by the possibility of tracing our journey through multiple frames.
