This just proves that we don't necessarily have to use toxic substances and electronic bits-n-pieces to have a really cool gadget that tracks global happenings.
Made of recycled metal plates and wood, this Antikythera Mechanism is a perfect replica of a 2,000-year-old calculator that tracked the moon, stars and planet's cycles. From Wikipedia:
The Antikythera mechanism (IPA: [ˌæntɪkɪˈθɪərə], an-ti-ki-theer-uh), is an ancient mechanical calculator (also described as the first known "mechanical computer") designed to calculate astronomical positions. It was discovered in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, in 1901. Subsequent investigation, particularly in 2006, dated it to about 150–100 BC; and hypothesised that it was on board a ship that sank en route from the Greek island of Rhodes to Rome. Technological artifacts of similar complexity did not reappear until a thousand years later.
In other words, someone really showed up the thinkers and garage tinkerers of the last couple thousand years, and it's only just now that we have a working replica of the ancient device.
It makes us ponder what other advanced gadgets we can make without any toxic or unsustainable materials at all. Inventors - get to the drawing boards!
