Installation art
Installation art is a kind of contemporary art which indicates a work combining various media in order to modify the experience of the spectator in a singular space or given circumstance.
Such installations especially developed in the 1960's, even if one can find earlier examples of this form of art with the objet trouvé of Marcel Duchamp or in certain surrealist artists.
The installations may be put in a scene, in an arrangement which has its own dynamics, often with traditional media like paintings, sculptures, or photographs, but more generally with modern media like video projections, sounds, or lighting effects.
