Starbucks Eco Thermos 

Designers Jang Jin-hee and Lee Min-jeong have designed a fantastic Eco-friendly thermos which actually monitors the amount of times it is used. The idea is to encourage you to use a tumbler as opposed to a disposable paper cup.

It uses a sensor in the base of the tumbler to recognise each time liquid is stored within. It then uses small LED lights in the shape of leaves to measure the amount of times which it has been used. The aim is that by the end of the year a map of the world should be revealed in lights.

If this goes into production then my name is most certainly on the list :)
