Love these two examples of time keeping outside of the box.
First up is a digital clock from Kibardindesign consisting of autonomous digits which each have a self-contained power supply. Able to be placed anywhere, light sensors will switch the clock to an invert mode: the figures are white in the dark time of day and black at daytime.
And then there's this beautiful calender from Oscar Diaz which uses the capillary action of ink spreading across paper to display the date.
Suddenly my Lumie doesn't look quite so cool.
