This piece is a changing one, it uses the lenticular technique, which consist in interpolating various images under a layer of micro-waving film. As we work on fold, the original idea was to take of every line of the fold and to keep only shadows. Then we wanted it to be a revelation of the illusion of the eyes, so the graphic kinetic choice : one image in black and white and the other is inverted... as moon phases : the result is a vibrating silver aspect due to lenticular film shine.
