I played with Lego a lot when I was a kid. An awful lot. My brother and I had several very large buckets of bricks, along with a couple of toolboxes worth of Technic pieces, motors, etc. It certainly made it easy for my parents when it came to buying me presents. Buying me a new Lego set or three was a guaranteed way to keep me quiet well into the new year and beyond.
Actually, it probably still would be, although most modern Lego sets tend to have so many custom pieces and pre-made bits of gubbins as to be almost pointless. I wonder if my parents still have my Lego Technic Control Centre…
Anyway. This guy is clearly mad. And a genius. Check out his Lego renderings of Escher. Incredible.
