30 days past September...

This is simply too amazing! This calendar was made by Spanish designer Oscar Diaz. Diaz designed a calendar that would cause ink to spread across the paper to reveal the date. The colors are based on a spectrum that relate to the temperature. Colors go from dark blue in December, green in the spring, to red in the summer.

Diaz's Ink Calendar will be shown at an exhibition called Sueños de un Grifo - Diseño con Alma de Agua that opens at the Círculo de Bellas Artes in Madrid from July 17th - Oct. 11th.
