How Long Is “Flux Re Flux”?

"A city, its crowds; crowds processed on film then transferred to video. I used a technique particular to video to manipulate a vertical section of the image sideways, changing both its shape and color density. Each operation was repeated a number of times, in a series of consecutive incrustations. The final image was achieved in a few hours, entirely by hand (or, more precisely, by hands), like an impromptu musical improvisation. The rhythm, the flux of the city confronted with video's scanning composition and compression." (Christian Lebrat).
