Circle circus is an abstract generative journey through space with visual and audible contrasts. An accompanied synth storm creates the atmosphere of a condensed science fiction movie, an odyssey into the mysteries of a vast void. These generative visuals are made to explore the geometry laws of a dome projection. A 360-degree projection on a vault is totally different from a plane one, allowing novel visual impressions. Thereto I pursue three approaches. On the one hand I emphasize the geometry of the vault and animate each spot of the projection. On the other hand incorporate free floating elements mutating in an organic way.
