The Credit Card Flashlight
Sometimes the light from your cell phone just doesn't cut it as an impromptu flashlight. Designers Hyun Jin Yoon & Eun Hak Lee have created a micro-flashlight that won't take up much valuable personal space (or resources). The Pocket light is about the size of a credit card, and is powered by a small battery cell. A light bulb shaped piece pops out and lights up, providing an easy source of portable illumination.
