This ink calendar uses capillary action to display dates: TOO clever!
[psfk.com] Designer Oscar Diaz has created an ink calendar that uses the capillary action of ink spreading across paper to display the dates. Each month, a bottle of colored ink spreads across a sheet of paper embossed with numbers, coloring them in as it goes.
The ink is absorbed gradually and the numbers in the calendar are printed daily, enhancing the perception of passing of time, not only signaling it. The ink colors relate to a color temperature scale with each month having a different color related to our perception of the weather in that month. So, December has a dark blue color while summers have an orange and red shades.
The Ink Calendar was displayed at an art exhibition at the Círculo de Bellas Artes in Madrid last year.
