When you are familiar with a city and your journey through it you begin to spot little things...
This morning on just after crossing the Millennium Bridge (just by the City of London School) I saw this piano/street art - complete with a hoarding licence (!). If I hadn't been in a hurry to get to work I would have stopped and played a tune (one of the two or three that I can play without music!).
On my way home from work this evening I saw this pigeon perched of top of a signpost - until he started grooming himself I thought that he was decoration, so perfectly in keeping did he look!
They have already cleaned the south side of St Paul's Cathedral, now they are working on the north side (the central part, below the dome) - you can see what a difference the work has made to the grimy stone.
