Shadowplay uses your finger's shadow to tell the time

We've already seen some nice looking light clocks, but this one requires you to actually stick your finger in it to be able to tell the time.

As we're about to enter a new year, nothing more appropriate than a post about a curious clock. Shadows have long been used to tell the time (in sundials)  but in this case we're facing an electronic clock that uses LED lights to cast shadows from your fingers acting as the clock pointers.

This clock was made as a prototype and it's unclear if it will ever become a commercial product. In any case, nothing stops you from creating your own. :)
