Ink Calendar by Oscar Diaz

Spanish designer Oscar Diaz 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 will be exhibited at an exhibition called Sueños de un Grifo - Diseño con Alma de Agua that opens at the Círculo de Bellas Artes in Madrid (17 July – 11 October 2009)
