Ambiguous Silhouettes

The movie demonstrates the depth ambiguity of the silhouette in the
centre which can be interpreted in two ways. The two interpretations
differ in the perceived order of the surfaces of the body in depth as
can be seen in the figure on the right. The left column illustrates the
interpretation in which we look at the figure's back in the first frame
(top). As a consequence, the figure rotates clockwise as we go though
the sequence of frames (from top to bottom), and we look at it from a
slightly elevated viewpoint (10 deg). In the right column we illustrate
the other interpretation. We look at the front of the figure in the
first frame, the figure rotates counter-clockwise, and the viewpoint is
10 deg from below.

Não é ilusão.. é farsa... patético na verdade... ela gira para os dois lados... observem apenas a bailarina da direita... quando ela muda de claro para escuro ela muda de direção... se vc ficar prestando atenção nas tres vai se confundir e achar que viu elas girando para as duas direções...

[havocker]

Uma pessoa não viu a bailarina girando...

@Confuzer I tested this by revisiting the site every so often, and I noted that it is completely random what direction they start in. In particular, it has nothing to do with what side of your brain is dominant, as some tabloids claim.
