It's fitting that an Apple software engineer would re-create what's possibly the world's oldest-known computer by using LEGOs.
Andrew Carol used around 1,500 LEGOs to re-create the Antikythera mechanism, a machine that ancient Greeks used to foretell celestial events. He made four gearboxes with 110 gears total, and when fed data, the machine will tell you when the next solar eclipse will occur. It's a beautiful and ingenious machine, and worth checking out the YouTube video. Maybe Carol's next project will be taking on the Mayans. You
