I went to the Big London Brainstorm in Lindsey Street, Smithfield yesterday, where lots of architects have had put forward their ideas for improving our city.
My favourite was the one suggesting that instead of building Renzo Piano's shard of glass, we should build a massive grain of sand. This would serve as a tribute to William Blake, and as a reminder to people that we are present in the universe.
Here is the quote from Blake's Auguries of Innocence:
''To see a world in a grain of sand
And a heaven in a wild flower,
hold infinity in the palm of your hand
And eternity in an hour.''
