This paper model is a Heavy Duty Super-Colliding Super Button, based on the video game Portal. The paper craft was created by Evgeniy Pelevin. Heavy Duty Super-Colliding Super Button is used within Test Chambers, and is activated when either a player or Weighted Storage Cube is placed upon it.
Buttons are present in the virtually all test chambers and, when activated, trigger a variety of effects. Buttons can either control the flow of Excursion Funnels, open and close hatches, release Weighted Storage Cubes, or even open and close the gate leading to the exit. It's up to the player to figure out how and when to use the button, or buttons, in order to proceed.
There are different kinds of buttons in Portal 2, which can be activated in different ways. The standard button can only be triggered by the player. A floor button can be activated by both the player and a cube, and cube buttons can only be toggled by cubes.
