Organic Art (William Latham and Stephen Todd, 1987) was reincarnated by the same authors with programmer and artist Peter Todd as Mutator2 (2013); Mutator2 was transitioned into VR as Mutator VR (2016) with programmer and artist Lance Putnam. The authors describe the graphics and audio systems of these works, particularly the procedural generation and visual effects and the creative exploitation of these effects within an art installation. The authors mix “real” and “unreal” features and effects, inspired by surrealist art, to create highly immersive psychedelic organic experiences for the viewer-participant.

Public gallery installation of Mutator VR creates special challenges.
