"Mutatis mutandis" is an interactive computerised installation. Its hypermedia project realised from digitalized video images and sounds. It addresses issues concerning poetry and philosophy, and explores the language of interact ivity in the making. The title is a Latin expression, used in French as well as English that means changing what have to be changed (or that which should be changed has been changed). This sentence underlines a paradox: in order to make a comparison one must ignore the part of the differences that isnt directly concerned by the comparison. The screen features a duo of images in the form of an diptych situated either in the upper half or the lower half of the scree. These images present a movement of transformation and thus display two different states of the same thing. By moving the arrow on the screen from one image to another this transformation is reproduced by the animation of the images, whereas by placing the arrow outside of the images a new diptych is displayed. The subject matter of these iamges is on the one hand singular - because it has been filmed in specific sites with specific circumstances- and on the other hand banal in that is represents everyday life and nature. During the consultation no particular theme concerning the subject emerges, except perhaps that of its interior mutations.
Each gesture of the viewer that provokes and repeats a mutation also changes a code number that is displayed in the empty section of the screen that indicates which new diptych sequence that viewer can, at that moment, summon up. The code that corresponds to each sequence indicates its place in the classification. The viewer is thus invited to experience a double attitude: to discover and understand the logic of the typology of mutations; observe attentively, but at a distance, a mere fragment of the complex real, that is irreducible to all description or classification.
