Spanish designer Oscar Diaz, based in London, has designed a calendar that uses the capillary action of ink spreading across paper to display the date. Each month, a bottle of coloured ink spreads across a sheet of paper embossed with numbers, colouring them in as it goes.

Ink Calendar make use of the timed pace of the ink spreading on the paper to indicate time. The ink is absorbed slowly, and the numbers in the calendar are ‘printed ‘ daily. One a day, they are filled with ink until the end of the month. The calendar enhances the perception of time passing and not only signaling it.  The aim of the project is to address our senses, rather than the logical and conscious brain.

The ink colors are based on a spectrum, which relate to a “color temperature scale”, each month having a color related to our perception of the weather on that month. The colors range from dark blue in December to three shades of green in spring or orange and red in the summer.
