London Laocoön

The Crossrail tunnels in London—for now, Europe's largest construction project, scheduled to finish in 2018—continue to take shape, created in a "tunneling marathon under the streets of London" that aims to add 26 new miles of underground track for commuter rail traffic.

It's London as Laocoön, wrapped in tunnel-boring machines, mechanical snakes that coil through their own hollow nests beneath the city.

What interested me the most in all this, however, was simply that fact that the first tunneling machine put to work in this round of excavation is called Phyllis—

—named after Phyllis Pearsall, widely (but incorrectly?) mythologized as the founder of the legendary A-Z book of London street maps.

There's something very Psychogeography Lite™ in this, weaving your city together from below with a giant machine-needle named after the woman who (supposedly) first walked the streets of the capital, assembling her book of maps, as if the only logical direction to go, once you've mapped the surface of your city, is down, passing through those surfaces to explore larger and darker volumes of urban space.
