Discouragement Redirection Cube



Discouragement Redirection Cubes are a new type of cube introduced in Portal 2. Like all cubes, they can be used to hold down buttons. They also have the unique ability to focus a Thermal Discouragement Beam and redirect it through their lens.

Each side of the Redirection Cube has a large, round piece of glass in the center. One of the glass sides is more curved than the others, being the lens that the Thermal Discouragement Beam is focused out of when coming into contact with any of the other sides.
