Neil sez, "Great chunks of Neal Stephenson's 'The System of the World' trilogy (review) use the Tower of London as a pivotal location, but I never got a clear enough mental picture of the place. So I photo-documented the Tower, with Flickr notes text extracts to provide a visual guide for the interested reader. The Baroque Cycle takes in a lot of the specific geography of London, and I'd love to see a collective gazetteer emerge, perhaps using 'baroquecyclelondon'
as a tag?"
(Thanks, Neil!)
