In 1901 a curious Mechanism was recovered from the Antikythera Shipwreck.   An analog computer built to calculate astronomical positions, its time of construction is now estimated to be between 150 and 100 BCE.   2000 years later, the mechanism was rebuilt using Lego.  Watch the whats and hows of the Antikythera Mechanism in this video :) The Antikythera Mechanism in Lego from Small Mammal on
