As a Lego fan and planning geek, I suspect I’m about as close to the target market as you can get for this product, which I saw at the NSS. Known by its makers as the “perpetual puzzle calendar” — presumably because there’s no official link to Lego — the compact desktop calendar can be taken apart and reassembled in different ways for different months.
They weren’t selling samples at the show, but I’ve since seen the calendar on Amazon. And I’ve admittedly got kids on the brain, but it strikes me as a great way to teach older children about the days and months of the year. (Or maybe I’m just trying to rationalize wanting one.)
