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 simple - 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.
