the zoomable paper map

Map 2 is a folding paper map of Greater London, with a twist (or rather, a fold): You can zoom in.

It unfolds from a little square into a bigger, four-sectioned overview of the city-center.

Any of these four quarters can then be folded out using a “patented folding” system to reveal a larger, zoomed version of the plan.

It’s as ingenious as it is low-tech, and probably well worth the £8 asking price.

The only problem I can see, as with most maps, is working out how to fold the thing back up once you've used it!
