Simple can be so cool. This Ink Calendar consists of little more than paper and a bottle of ink, yet keeps you up-to-date for an entire year, even displaying what day of the month it is, all sans energy ...
Designer Oscar Diaz created this simple calendar wherein each month a bottle of colored ink spreads across a sheet of paper embossed with numbers and colors them in.
The calendar is shown as part of the SUEÑOS DE UN GRIFO exhibit at the Circulo de Bellas Artes in Madrid and is on view until October 11, 2009.
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.
