“Retournement” is a syntactic animation from 1991. It is not the movement of words on the screen that counts in the syntactic animation, but the syntax changes that movement entails. So, reading by following the words with his eyes or performing a spatial reading of the screen "product" different texts. The reading may switch at any time between these two modes. So, the number of texts contained in these some words is uncertain and it is impossible for the reader to build all while the movie is playing. This is a non-algorithmic type of generator for which the reader himself is the inference engine, and that only a space-time processing of language allows. At times of the animation, the meaning can be seen as optimistic or pessimistic depending on the method of reading; a verb can even become its own subject, making performative the sentence. All this happens in a visual time gesture that is something of a caress that an improvisation on the violin emphasizes.
