Here's a really great perpetual calendar: "at first glance, the blind date calendar looks like a series of odd shapes inside a frame. but what is this picture? is it a work of art? a code in Braille? actually, it's a calendar that lasts for an entire year and is completely re-useable. the secret lies in the magnetic frames that come with the calendar-- simply roll them over the black signs to discover the dates. a handy "blind date key" is included with the calendar that discloses the dates and names of the months. if you or someone you love needs a re-working of a standard office or desk accessory, look no further. this is it."
