Throughout this multi-media interactive installation, we are ineterested in "the theory of information", and and its problems of the transmission of the information of a transmitter towards a receiver. Developed by Claude Shannon in 1940, this theory aims to define and quantify the quantity of information contained in a physical signal, for exemple a sound or an image.
The physical data storage takes place by a numerical phase of compression which reduces information in a minimum of symbols measured by its minimal entropy.
For an image, this decomposition is geometrical and is translated on the elementary surfaces of small size: the pixels.

18 pixels²x2 uses this process to split up an image then invites to its reconstitution by the public which becomes the holder of essential information. .
The totality of this image, on minimal entropy of 320 pixels, thus depends on the number of visitor detected by a photosensitive sensor.
Thus each spectator starts, by his entry in the room, the random selection of a pixel and sound which indicatesthe coordinates of the chosen pixel.
The source of information, visual and sound, from this image-phoenix in becoming is extracted from 4 films made to Beijing in May 2004.

Each image-pixel corresponds then to a fragment of memory of this voyage in China.
