Antikythera-prototype ancient computational device

The Antikytheria mechanism is a fascinating piece of ancient technology- found on a shipwreck off the Greek coast in 1900, it was another 70 years before historians realised it wasn't simply a lump of corroded bronze but actually a complex computational device designed to predict astronomical postions and eclipses. If you'd like to find out more about this really amazing piece of ancient mechanism, have a look here.

This is my imagining of what a prototype Antikythera mechanism might have looked like- apparently such a prototype device might actually exist but I highly doubt this looks anything like it! If you would like to own it though, it's for sale here.
