This Heat-Sensitive Map Changes With the Weather

The weather can fluctuate in an instant and, as Murphy’s Law goes, you’re bound to be caught unprepared—underdressed, overdressed, or without an umbrella. But with this heat-sensitive map in hand, you’ll always know where to take shelter—and do some exploring while you’re at it.

The “BATH °C Thermo Colour Map,” created by recent Kingston University design grad Camilla Hempleman, reacts to temperature changes to display different places to visit across the city of Bath, England. Between 25 and 30 degrees Celsius, the map glows pink with rivers, lakes, and other outdoor sites; at 15 degrees Celsius and below, it highlights indoor attractions clustered in the city center. When it’s raining, the map shows museums and other buildings where you can stay dry.
