Michael T. Wright, a former curator at the Science Museum in London, reconstructed a model of an ancient astronomical calculator named the Antikythera Mechanism. It gets it's name from the Greek island where it was found. For fifty years after it was recovered by a sponge diver in 1902, researchers had no clue as to it's possible function. By that time the ravages of two thousand years of being at the bottom of the ocean took it's toll through the effects of corrosion and mineral deposits. It wasn't until HP took reflectance imaging scans of the device there became clear enough picture to construct a working model. Wright's reconstructed model has the capability to predict the yearly motion of the sun, moon, and five planets, and is also a calendar.
