A pretty cool concept watch designed by a French for the Japanese brand Tokyoflash (the best Japanese gadget brand of course ;) ). The “Plasma Watch” shows the time by two small balls that act as needles. But these small balls are electrodes that can direct the flow of plasma that is activated by touch! Obviously the system of plasma is switchable off to avoid draining the clock, which charges via USB. A very good concept, the question remains whether it is achievable!
