Puzzle elements

Overview

As you enter the puzzle, you find yourself in a circular arena, like an open-air amphitheater. There is a circular structure in the middle, with two blue doors. One of the blue doors gives access to an RGB converter and a blue emitter, and is activated by a pressure plate in front or a red receiver to the side. The other blue door gives access to a connector and a green emitter. That, too can be activated with either a pressure plate or a green receiver to the side. Near the back is a red receiver connected to an angled fan pointed at the progress wheel, which is suspended above the central structure.
