Pointed out to me on the tube sometime last week, it was with great pleasure I stumbled across these yesterday afternoon.

The original animal, the elephant was discovered while Paul Middlewick was staring at the tube map during his daily journey home from work in 1988. Created using the tube lines, stations and junctions of the London Underground map there are now 32 different animals, all featured on the site.
