The work is composed of a video monitor with a webcam aside, and a computer.
By default a black image it's visible, a foggy layer hiding a reflection of what is in front of the monitor. It shades the whole image except for what is moving, the only way to see thru it is to perform a physical action. In this way the audience can see his walking reflection, his Doppelgänger.
This image is reflected by a three dimensional virtual liquid, a narcissus water mirror, which waves, responding to movements.
