I have run across a Youtube video of the 2,000 year old Antikythera computer from Greece.
A gentleman has reconstructed the devise and shows its operation.

While watching this video, I was amazed as I watched the hands moving. Observing the hands
and the circular shape of its center, it it almost looked like a crop circle formation.
Is it possible that a crop formation, showing hands in a certain position, could actually show
a time that can be figured out using this found device? maybe a time or date of return or of
an event of somekind?
 
Just curious and thought I would pass on my thoughts and/or ideas.
Love the show on History channel!
