There are two pressure plates, one in the front of the room and one in the back, each controls a blue door that blocks laser from being transmitted from one fixed connector to the other behind it. There are two red receivers and two blue receivers in the central tower, each controls a horizontal blue door, and they alternate. At the very top of the tower is a hexahedron. At the very back of the room is an elevated area, on which you can see the Sarabhai Fragment.
