London is dizzyingly complex, so maps are a must even for locals. Usually, they're clunky mini books. But the Map Squared solves that problem ingeniously.

Each sector of the map can be unfolded, for a zoomed-in detail:

The folding technique is apparently patented and available for licensing--the applications would obviously be vast. Wonder if you'll see this everywhere one day?

Probably the cleverest map we've seen since this one. All of which just serves as a reminder: Amazing interaction design needed be complex. I doesn't even need to be high-tech. And in retrospect, it's probably stunningly obvious--Which is the mark of any great design.
