This clever clock doesn't look like a clock at all, instead looking like a painted light bulb that reflects its light back on the wall. And that's what it is, really! But in those shadows, you'll find a functioning clock.
Yes, the "hands" of this clock are really shadows projected on the wall around the bulb. The shadows are of different shapes and lengths, representing the hour, minute and second hand. The front cap is removable for replacing the batteries and adjusting the time, and you can modify the length of the shadows as well. LINK
