As electronic devices capable of projecting images get smaller, projectors will be showing up in unusual places—maybe even your wrist. This concept for the Ex-Time projector watch by Designer Rong Yong has numerals on one side of its exceedingly thin bracelet, scrolling the time and date in an easily visible format.
On the side of that bracelet is a tiny lens with a projector behind it the size of a fingernail. Push a button on the watch, and it projects the time or date onto your hand, or even onto a nearby wall. We'd like to see designer Yong add a tiny microSD flash memory slot to his design, so we could load movies onto it and project them on the wall, too.
