Projectors are getting smaller and now we even see them fitted in to mobile phones. The Ex-Time concept takes a similar idea and puts it in to a watch. The face of the watch shows the time, date etc... in scrolling format. On the side of the watch is a lens with a tiny projector behind which projects the time and date on to your hand or a wall. Although a little crazy, it is one idea of where you might find a projector squeezed in to in the future. I doubt we will all be sat around someone while they keep their hand steady so we can all watch the latest movie.
