The Coolest Calendar Ever

504x_INK_CALENDAR_OSCAR_DIAZ01

Created by Oscar Díaz—the 420 X 595 mm Ink Calendar actually works. Oscar says that it’s not designed to be one month only, but the whole year. 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.
