Twenty-One, Mosaic: In that special place where LEGO and mathematics meet lies true geek.
Can a square be partitioned into a number of smaller squares such that no two of the smaller are the same size? Casual pondering might lead one to think this geometrically impossible. […]

This guy is a professional LEGO artist. Seriously.
