A  Mirroir  "A", the second  lettre  of  CIRE , appears from the  vide   centre  and rolls out on  blanc  rails, a  missile  ready to be launched. Each "A" looks like itself. A solitary  mots , indicating something that isn't there. Its not an object, though it does have the  substance  of a  lettre  (in the thinking  sombre  of this frame).
