fiddling

I'm toying with a proof-of-concept web app for anonymizing pictures by pixelizing them. Here's an example. Can you figure out who the person in the picture is?

You can drag around the pixely part.

Without viewing source, can you guess how it works? I'll give you a negative hint: no HTML canvas or plugins involved. Don't read the comments if you don't want to see a spoiler...
