That's pretty neat.

Not quite as neat as if they had been formed by actual, working subway lines, but nevertheless pretty neat.

Oh, I'd forgotten about this. When my niece is slightly older, I'll print some of these off for her and get them laminated. At the moment she's too young, so I've been finding cool photos of animals on Flickr, printing them off on a colour laser printer and laminating them so she can look and learn but not trash them.

What, no mole rat?

Nekkid, or otherwise, apparently :) Occasionally you can see the odd rat scampering around between the tracks on the underground, which is always an extra-special treat...

Its incredibly disappointing that the elephant goes nowhere near Elephant & Castle.

That is not at all what I expected, but it's quite nifty. Thanks, Daniel!
