Video of the Week #63 October 3rd, 2012: From: Watch the Most Amazing Lego Contraption Ever by Michael Moyer at Observations. Source: Akiyuki First there was the video of the LEGO version of the Antikythera Mechanism--an ancient Greek computing device found in a shipwreck in 1901 used to calculate the positions of astronomical bodies with extraordinary precision. This new device does little more than move plastic balls from one place to another, but we relish its sheer complexity. The machine took 600 hours to make and moves the balls around a 31-meter-long pathway.
