Small cameras were all the rage last time. Now, smaller is better. Meet the Ubi-camera.
You connect it to the your index finger, then make a rectangle with the index finger and thumb of both hands, and press hard with your thumb to snap a shot. I can foresee much potential for this device. It will probably start off with an average megapixel quality, and then it will slowly improve in newer models, after which bluetooth/wifi/infrared capabilities will be thrown in, and viola, a small portable camera that can be hung around your neck.
You can find out more info here.
