The Witness is an upcoming three-dimensional (3-D) puzzle video game by Jonathan Blow, an independent developer and the creator of Braid. The game was announced in August 2009 and is scheduled for release in 2011. In interviews, Blow described the work as "an exploration-puzzle game on an uninhabited island."
On 28 February 2010, the official The Witness website uploaded Eric Urquhart's conceptual artwork portraying a variety of 3-D environments. According to Blow, the game would feature "a graphical style that values simplicity," suited to "mellower environments, with both indoor and outdoor settings." Another designer, Ignacio Castaño, was revealed to have been working on a rendering system for the in-game global illumination and visual effects.
