The subways round the IMAX cinema have been treated as a lighting installation. The lights change gradually from one colour to the next. if you look at the green image below you can see that it has just started the red sequence. Very slowly, bulb by bulb, the lights will switch from green to red until the whole subway is glowing red. It was fascinating to watch but still had that creepy feeling that seems to emanate from subways and underpasses.
