Ideas in your pocket
The credit card sized Pocket Light by Eunhak Lee & Hyunjin Yoon, powered by a tiny cell, can be easily switched on by popping out the light bulb shaped cutout.
Whether you want to make an impression with incredibly cool (and somewhat expensive) business cards, use it as a reading light, make a point whenever you come up with an idea or just show off in front of friends, its purpose is entirely up to you.
The best part: the entire concept is actually quite doable and the designers are currently looking for a manufacturer. We wish them the best of luck!
