Why didn't they just make an exact duplicate?
No too say it isn't a correct conclusion. But I'd still be careful about accepting the sweeping conclusions some people are making about the device.
I very much agree, but let's be fair; they don't have all the parts, and there's still some debate as to what it's exact
function was. Obviously, it was some sort of heavenly-body-tracking thingummy, but exactly which
, and why
is still up for discussion without a complete device (well, the why
can be put down to simple scientific endeavor, but still...). All the replicas made so far, therefore, cannot
be exact replicas, and never can be unless we find an identical device that is complete or the original blueprints.
I concur with thinking it's amazing enough these folks were able to replicate what is
known about it's function with just off-the-shelf lego technic parts. Nice find, Ren!
