We're not really sure how this works, and since it's a concept, I guess it really doesn't have to. But for now, we'll just look at the pictures and say, "Whoa, Cool!" The Pocket Light is designed to be about the size of a credit card and powered by a small cell. Flip up the light bulb-shaped cut-out to switch on a soft glow perfect for emergency power outages or finding an earring in a dark bar.

The Pocket light is from Hyun Jin Yoon and Eun Hak Lee at Yanko Designs.
