Here’s a curiously interesting product idea, a coffee tumbler with LED lights built in. But there’s a reason the lights were put there.
As you pour a hot beverage into the cup, the LED lights come on and show a part of the Green World map front and center on the tumbler. Each time you refill the cup another light comes on and so on, until the whole map is displayed on your cup. This could be quite fun and a cool way to showcase environmental awareness. It’s from Yanko Designs.
