Monoculight

This is my entry for the Thingiversity Technology S.T.E.A.M. Challenge:
LightItUp. The assembled part is a functional light-up eyeball
demonstrator to encourage kids of all ages to think about how basic lens
technology works and how the marvelous biological optical systems in our
heads (aka our eyes) enable us to see.

I've blogged my development progress at http://monoculight.tumblr.com
which is also available as a PDF document in the Thing Files as
"Monoculight-Development-Blog.pdf".

Abbreviated build instructions are provided under "Instructions" and the
full detailed build instructions including figures are available in the
Thing Files as "Monoculight-Documentation.pdf". This document also
includes a complete description on how Monoculight is especially
relevant to the MakerBot Technology Challenge.

This was a fun project in which I had to develop a lot of technology
(printing hemispheres, snap fit features, battery holders, circuits, CAD
