Champing at the bit for Crossrail? There may still be a little while before London's behemoth subterranean rail network gets going, but here's a glimpse into the near future:
The artwork, by 3D Joe and Max, can be found outside the Museum of London Docklands, in east London right now.
It's been commissioned to remind visitors that the museum's Tunnel: The Archaeology of Crossrail exhibition ends on 3 September. Look closely, and you'll see the artwork also features archaeological objects discovered during the digs, on display at the exhibition.
Crossrail trains will indeed pass roughly beneath this location, as they make their way from Canary Wharf to Whitechapel (or vice versa).
This has got us wishing for some glass cutaway sections in London's pavements, for when the real Crossrail gets underway. Come on TfL, make our pipe tube dreams come true.
