What you're looking at is a fully functioning Antikythera Mechanism, built with LEGO blocks.
The Antikythera Mechanism was built in Greece around 100 BC and is the oldest-known scientific computer. It was recovered from a shipwreck in 1901, but it took over a century to fully understand its purpose. The machine is an astonomical clock that determines the positions of celestial bodies with a precision that can only be described as pristine. In the example above, you'll see that it can predict a solar eclipse in 2024 down to the half-hour.
I'm reminded of a geeky quote from Ghost in the Shell 2: Innocence (highly recommended): "What the body creates is as much an expression of its DNA as the body itself."
What are we expressing? What are we playing with?
