L'Amertube is a formalist work that uses video as a creative medium. A succession of forms shaped by lines of white light are produced by video feed-back. These forms move in a circular manner and give the illusion of existing in a three-dimensional space. A horizontal line that divides the screen renders the forms more complex, and electro-acoustic music follows the transformations. For videographer, Jean-Pierre Boyer, this is not about reality itself, but about a construction of reality.
