Rotation about the Y (vertical) axis of a tridimensional fractal aggregates that can also be viewed as a set of 4x3 pseudo-stereograms [Rotation autour de l'axe Y (vertical) d'agrégats fractals tridimensionnels qui peut être vue aussi comme un ensemble de 4x3 pseudo-stéréogrammes]
.
is a "true" stereogram
