Strike a light!

You don't have to be crackers to work here, but it probably helps. The pavement lights under London Bridge (two days ago) reminded me of another place with lights in the floor.

This is the Trade Union Congress building in Great Russell Street. I just liked this shot a lot more that the one that showed the coloured lights.

For people wondering, "Tuc" is a brand of cracker.
