Ink Calendar Counts with a Slow Flow of Ink that Precisely Counts Each Day

Designer Oscar Diaz has designed this Ink Calendar that uses the capillary action of ink spreading across paper to display the date.
A jar of ink, with the month marked on it, is placed on a special piece of paper with the day numbers embossed in one continuous line. Slowly, the ink spreads until the month is over.

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