The ViLIGHT Watch from Menghsun Wu features a unique face that tells time using natural light. The light passes over the three openings in the watch used to tell the hours, minutes and seconds.
Wu says that the ViLIGHT Watch is based on the human eye, but I personally think it looks more like a sundial. Regardless of its inspiration, the ViLIGHT Watch is a cool design that I wouldn't be surprised to see on store shelves sooner rather than later.
