Oh, to have enough time in the day to spend on this Mintpass puzzle calendar, which takes inspiration from those sliding-puzzle games we had as kids...only this time, with the day's date. Yes, really.

With 41 puzzle-bits (and one space for allowing them to slide about), the idea behind this calendar is pretty simpleā€”until you have to change the dates around for the next month. At least they've thought to include a "help" break on the bezel, which lets you pull out all the pieces and arrange them properly...rather than spending hours trying to slide them into place.
