You can plan ahead all you want, but a vacation is often at the mercy of the weather wherever you’re traveling to. And that inspired designer Camilla Hempleman to create a special map, printed with thermochromatic ink, that changes color to reveal the best places to visit based on the local weather.
Remember those Thermochromatic t-shirts from the early '90s? Unsurprisingly, American Apparel started selling them last year. Now there's a sofa version from NunoErin, which is coated in a thermo-sensitive finish that changes color where your body touches it.
