Prisoner's light is a visual representation of the "pay-off "within the prisoner's dilemma.
The aspects of this 'dilemma' are explored through a 'non-collaborative' game.
Two prisoners are questioned individually. Each one of them on their own are forced to make a choice, while being simultaneously influenced by a "third party"(warden), thus obscuring their true 'good' intent. This interaction between characters can be representative of user & designer (prisoners) as well as of the purchasing audience (warden) within the design industry.
