end(O) is an original and immersive piece specifically created to be performed at the Satosphere. It merges the aesthetic research and techniques of musician Alex Augier and visual artist Alba G. Corral into a transversal and coherent artistic proposition that gives an original and specific voice to hypermedia. In this piece, the artists control sound, image, space, and time to create an organic and poetic work of hypermedia in the Satosphere. Instead of using image and sound for their illustrative, informative, or narrative aspects, the piece takes an original path specific to hypermedia: no single dimension dominates another; instead, each element of the piece completes and enriches the others.
