The Perpetual Calendar by American paper and animation artist Norma V Toraya (CrankBunny) is a great paper saving innovation that will hopefully discourage the surplus of calendars that exist on the planet.
The mechanical paper calendar allows you to keep the same calendar until 2030; by utilizing a simple dial system so that you can continually match the correct year to the correct month, year after year (or at least for roughly another eighteen years).
The 8.5x8.5inch (21.6cmx21.6cm) Perpetual Calendar retails for US$15.60 (€11.20).
