Emerging from a technicolor meal in Docklands - part of which is pictured here - I was confronted by the dizzy brightness of Canary Wharf. On the back of a disturbing magic mushroom experience - a Turkish meal that in some parts was toxic yellow and in others a pale brown concealed under a grey lumpen glop that looked like Dracula vomit - the skyscrapers of Mammon felt almost friendly. If beetroot turns your pee red, what does the spectrum of E numbers, masquerading innocently behind nursery colours, do to the more serious stuff that comes out? An interesting thought to sleep on on a Friday night;-)
