I agree with swissmiss: this simple clock concept is awesome! Each number has an individual case (with independent mechanisms) so that they can be hung as close or as far apart as you like. Its sleek autonomous design means you can attach it to any surface you like. Not to mention the fact that it reads the light in the room and knows when to switch the numbers from black (daytime) to white (nighttime) automatically. Love it!
