Prague-based designer Vadim Kibardin was listed by Wallpaper magazine as one of 40 designers "who will change the world". Of course that remains to be seen, but this concept for a digital clock is pretty sweet.

The Black & White clock has only the necessary 4 seperate numbers, needed to tell the time. No case holding them together or anything. It has one subtle extra feature: a light sensor should invert the figures from black in the day light, to white when the room is dark at night.

Vadim Kibardin is still looking for a manufacturer.
