en Altadefinizione. Han closes a trilogy that began with Ere erera baleibu... (1968) and continued with Impressions en haute atmosphère (1991), which goes from the microcosm of atoms (Ere Erera) to the macrocosm of cosmic galaxies. After an "informal" abstraction obtained through the projection of fine particles on a transparent film tape from which all notion of form is shunned, the artist reintroduced in his following movies simple shapes, circles and spirals, coils, reproduced according to the most traditional technique of movement decomposition (animation cinema), which "channels" Brownian motion of matter.
