Estereoscopio de Wheatstone 'Revival'
  We describe the making of a two-mirrors stereoscope, identical to the first historical one, with the advantage of employing digital images on LCD monitors. We surprised the public with it, because they do not imagine being possible to watch 3D without needing goggless, neither the lack of knowledge of something so simple and old. Nowadays it is common to have two monitors at the exit of a computer, so that the system is still a simple one.
