Escher Paintings with Lego Bricks

sciuro writes "a couple of guys (A Lipton & D Shiu) have built three of M C Escher's 3D-distorting paintings using Lego bricks (and some carefully chosen camera angles). Balcony, Belvedere & Ascending and Descending are all down at the bottom of the page. Nice!" Some other pretty pieces as well.
