Portal 2 Puzzle Maker/Flip Panel

Flip Panels are a test element in Portal puzzles that on activation switch between showing a portalable or nonportable surface.

Flip Panels can be placed on walls, ceilings and floors. They show either a white portalable or a black nonportalable surface. The color the Flip Panel starts with is changed the same way like for ordinary surfaces: either rightclicking on the Flip Panel and ticking or unticking "Portalable" or by pressing "P" on the keyborad.

In order to work, Flip Panels must be connected to another test element like a button or a laser catcher that activates them. When the connected test element is activated, the Flip Panels flips around and shows the opposite of the color it started with. When the activating test element is deactivated, the Flip Panel flips around and shows the surface color it started with again.
