Here is a view of the top works of the “Bipolar Brain” upside down. The bears are not mounted, which accounts for the open hole. The little tubes are are for the cables that push and pull the head lobes open. The tubes are needed to constraint the cable as it pushes up to open the head. Without them the cable buckles sideways. By constraining them in a tube the force is directed upward instead of sideways.
The two brass arms on the left are to rotate the eyes.
