Wow. Just came across this - 'The Sandpit', a day in the life of New York City, in miniature:

I'm still trying to get my head around how he's made it look like it's a tiny model, when in fact it's the real NYC. It's something called 'tilt-shift' - the narrow depth of field emulates the effect you get in macro photography - when you photograph something in macro, you generally get a very small area that's in focus, and the rest is blurry. Something like that. There are special lenses for this stuff, but apparently it's possible to it post-production, too. I must give it a go sometime, because I've never quite got the hang of making landscape photos look interesting. They're always so flat and boring.
