Black & White Clocks by Kibardindesign

Designer Vadim Kibardin of Prague, Czech Republic studio Kibardindesign has created Black & White digital clock concept that uses only figures without any case. Each digit has self-contained power supply and independent control, it can be fixed to any surface autonomously. A light sensor will switch the clock to an invert mode: the figures are white in the dark time of day and black at daytime.
