Petko Tanchev is a visual artist, scenographer and video designer from Plovdiv, Bulgaria. He uses computer hardware and visual programming tools to create generative images, interactive systems, animation and video. The virtual worlds Petko creates reconsider the aspects of the physical reality adding a different meaning and content to it. He often works in the specifics of a particular space (site-specific) and is always willing to experiment with new media and contemporary technology. Another reincarnation of Petko is nemko-fi which is a part from the audiovisual collective Melformator.
