Basically the Space Core from Portal. I don't need it so round, and it would be nice if it were sort of Minecraft style. Note the axis that the rig needs to spin on for the "eye".
quick note, the eyelids are attached to the area highlighted in red, same with the eye
Also, I do know of the core rigs already made, but as far as I know, they don't spin on that axis or have adjustable eyelids which is what I need
