I’ve been playing with panoramas a lot recently. I’m not a very good photographer, I don’t have strong visual instincts, so panoramas — for me, anyway — are a way of creating interesting scenes. It’s a cheap trick, but then, I’m a cheap date, so I suppose it’s all even.

Anyway, a group of people far more talented and industrious than I have upped the ante with the world’s largest 360-degree panorama — a ginormous 18.4 gigapixel image of Prague that you can navigate much like a Google Map, but with far, far more detail. In fact, there’s so much detail that the photographers have put together a treasure hunt with a $1000 prize.
