Just incase the world needs yet another photo of the Mathematical Bridge, Cambridge, here it is.

Viewed from Silver Street bridge, the official start of 'The Backs'. Behind me is one of the main punting stations on the Cam and the weirs of the long demolished watermills on the edge of the city's beautiful water meadows.

A good wikipedia page on the bridge's history and mythology.
