Word-a-day calendars might improve your vocabulary, but unless they're electronic, they're not exactly great for the environment. Here's a more creative and lasting alternative that you don't have to wait for a new year to try out: the key calendar from Takumi.

I'm not sure exactly how it works, but it seems that you move the key every day to keep track of the date. It would be very cool if turning the keys revealed some kind of secret compartment (you could set it to deliver a love note on your anniversary or something) but I don't think that's an option yet.

Apartment Therapy says the calendar "plays upon both the metaphorical and also the innate physical desire to manipulate the mechanical as an effective way to keep track of the days of a month."

I just think it's pretty.
