You have got to love the way Old Father Thames is flowing back into the centre of London life. I walked from the National Theatre over to embankment yesterday and it felt vibrant and beautiful. The Royal Festival hall is being spruced up, the underrated Golden Jubilee footbridge was full of kissing couples and the London skyline was glittering.

And now there is another wonderfully ludicrous new project proposed for the stretch of river between Waterloo and Blackfriars Bridges. The proposed design has been created by the Metropolitan Workshop and consists of a mad web of cables, along which run champagne-bubble cars to a suspended bar. So picture yourself in a bar on the river, with tangerine trees and marmalade skies... (sorry!) Sounds pretty far-fetched, huh, but then again who would have predicted a giant bicycle wheel in the middle of the Big Smoke?
