Antikythera Mechanism in Legos

A very sharp correspondent points me to the post on the fastcodesign site about building a model of the Antikythera mechanism using legos. Watch an Apple Engineer Recreate a 2,000-Year-Old Computer Using Legos  I have written about the Greek mechanism, found on a shipwreck, before.   An anthropology prof showed us a picture of it in the 70s and asked us for ideas about what it was meant to do.  Only recently have a number of researchers, including some at HP, discovered its use as an astronomical calculator.   Likely used as an aid for navigation.
