For his latest installation Spanish designer Oscar Diaz designed the Ink Calendar that uses capillary action of spreading ink across paper to display the date. Each month uses a different vial of temperature controlled ink that travels across embossed paper and colors in the date.

The ink colors were designed to relate to our perception of the actual weather on that particular month. The colors range from dark blue in December to shades of green in the spring and oranges and reds in the summer months. The projects’ focus is to address our senses and our perception of time passing by.

The Ink Calendar is part of the Suenos de un Grifo that is now open at the Circulo de Bellas Artes in Madrid, Spain. The exhibition is open from July 17th 2009 through October 11th 2009.
