Lenticular maps

Lenticulars, also known as “winkies”, are those goofy quasi-3D plastic gimcracks that are good for two-step animations showing things like Jesus looking up to heaven or dancing girls wiggling their hips. I never thought they’d be useful for anything but cheesy gimmicks. But they turn out to have numerous cheese-free applications in the modern world. For one thing, you can now buy a Sharp laptop with a three dimensional lenticular display. And then there’s this nifty lenticular map of Manhattan in which three different maps come together in one virtuous unit: Urban Mapping. Make sure and run the Flash demo to see how it works.
