It took us a while to work out what this is. It seems to be a promotional installation for capturing images and it was only by watching the Chinese interact with it that we could work out what it did. There was nothing revolutionary about it but it seemed by the crowds who were interacting with it that it was very popular, although only temporary. In the image below you can also see what appear to be little crosses. These have been filled with all sorts of images from the Olympics. It seems so strange to view what is happening back in London from the streets of Beijing, but one thing is clear from what we have observed, and that is that they are Olympic mad here.
