This keyring, or should I call it clock or a projector? Projection Clock Keyring projects the time to the wall (up to 2 meters away).

You won’t need to turn your bed side light at night to find what time it is. All that you have to do is. All that you have to do is press the button and a clock will be instantly projected on to the wall. You can even change the display to show the date, or a seconds counter!

It is also very small (30×30cm) and you can but it here.
