Inspired by vintage flip calendars of the 60's, this desktop calendar will show you the current date and month. Flip it, and it will show you the next date. You will hear a gentle thud as a number card falls into the lower chamber to make room for the next card.
This calendar requires no batteries, the force of gravity does all the work. See the video!
UPDATE: We now have the month rings in Spanish, Italian, German, French and Russian. Please visit http://www.otvinta.com/download04.html to download them.
