Sitting up on a podium for two longs days, as I did this week, means that you get pretty familar with your surroundings. So it was that I discovered the smiley doors (see picture). Jacques Tati would have been proud. For those not in the know, in Tati’s Modern Times, the round windows of a modern house become eyes, and the heads of people walking behind the windows become eyeballs, so that the house itself becomes an animated face. At times, with people walking behind the doors, it really did look as though the eyes were following people around… Thanks to Paula for the photograph.
