Metamembrana is an interactive audiovisual installation which consists of a projection and various interfaces, a landscape full of situations enabling the spectator to choose which route to follow and construct his/her own story. Drawings, murals, actors, fire dances, aesthetic irreality, etc. make up the formal narrative of this particular project and the elements around which the spectator must play with. Technology applied into arts, Antúnez integrates more complex and sophisticated technological resources in his projects.
