London is generous with its culture. Many of the museums allow free entry and there are seasonal events that cost nothing to attend and enjoy. But it's London's public art which provides some of the richest sources of inspiration for me. It's the element of surprise that does it.
I usually don't set out to find these monumental works. I turn a corner on foot, or come down the street on the top deck of a bus, and am arrested by the sight of a wing sprouting from the pavement or a strange sunburst of flaming tentacles made of glass.
