If you’re Andrew Carol, it’s Lego. In his spare time, the Apple software engineer has taken to recreating a complex computer that originates from 100 BC. Back in the day, the highly intelligent mechanical computer was built by Greek engineers to predict celestial events and eclipses with unprecedented accuracy. So, how did Carol do it? Check out this film to see the spectacular plastic mechanics in action. And if you really want to get into the mathematics behind the creation, click HERE.
