Why check your smartphone for the weather when you can look at 6,000 windows lit up with 72,000 LEDs? If you're anywhere near the Dexia Tower in Brussels, a glance at its various colors immediately lets you know what the weather will be like the next day.

This relatively cost-efficient installation uses a dozen LEDs at each window, and the way the light reflects off the closed windowshades gives it a bright yet pleasingly gradated appearance.

It's quite arty looking, and as soon as local residents learn the code (that still remains a mystery to us), they'll be able to tell just by looking at this building what the temperature, humidity, wind speed and precipitation will be tomorrow.
