THE PHENAKISTOSCOPE CARD

Card included in the XQ forty-nine Deck

The phenakistoscope uses the persistence of motion principle to create an illusion of motion. Although this principle had been recognized by the Greek mathematician Euclid and later in experiments by Newton, it was not until 1829 that this principle became firmly established by Joseph Plateau.

In order to see the animation on the card you need:
- the Phenakistoscope card of the XQ forty-nine deck
- a spinning movement of the card, for example use the card spin flourish
- a mobilephone to film. View the rotating card through a cameraphone
  or any other camera with a digital display shooting at 30FPS and watch the card spring to life.
- bright light. The brighter the light, the clearer the animation will appear.

AUTOSTEREOGRAM CARD NO 2

Card included in the XQ forty-nine Deck



An autostereogram is a single-image stereogram (SIS), designed to create the visual illusion of a three-dimensional (3D) scene from a two-dimensional image. In order to perceive 3D shapes in these autostereograms, one must overcome the normally automatic coordination between accommodation (focus) and horizontal vergence (angle of one's eyes). The illusion is one of depth perception and involves stereopsis: depth perception arising from the different perspective each eye has of a three-dimensional scene, called binocular parallax.
(https://en.wikipedia.org/wiki/Autostereogram)

How to see the autostereogram:
- Relax your vision and unfocus your eyes. Look through the card, as if your eyes are focusing on a point
  behind the card.
-Keep looking at it this way until your focus adjusts and the hidden 3D object becomes sharp and recognizable.
