Photography buffs might be interested in this one: a light system designed to be used with the Nikon 1 and Coolpix cameras. The LD-1000 is an ultra-portable light system that you can use for making short movies or doing some close-up photography. It can be used either off the camera or connected to it through the tripod socket. It’s a bit easier to deal with than a separate flash, because you can easily adjust the angle or position to get different lighting effects. It’s gentler too, so you can avoid that washed out startled look the flash can often result in.
