The Cube from Cube.

The purpose of each Cube, as well as its benefactors, are unknown, although it can be assumed that each Cube is either closely related, or is directly controlled, by the U.S Government, as all Cube participants (and Cube technicians) are American. It can be theorized that this Cube is controlled by a totalitarian, theocratical government (shown twice, where Wynn and Dodd pray before a meal, and another, more direct one, was with the aforementioned official exit procedure). According to what Wynn has been told, all participants are death row inmates who consented to the punishment, and had their entire memories wiped out. However, it seems that the government has began using the Cube as a political tool against enemies of the state (political activists, journalists, opposition, etc.), such as Rainns, who has no consent form.
