watch as one listens

The starting point of the sequence consists of four fixed compositions already presented as such in old articles in the "drawings" section.

At the beginning of the animated sequence, most of the constituent elements of the compositions overlap to form a relatively uniform frame.

Then a first composition gradually emerges in its integrity, but for a short time because another replaces it progressively.

And so on... to a final new composition, which is built from elements of the first four and which colors undergo various transformations themselves.

After the pure geometric forms of the rectangular lines and surfaces, here is a kind of organic fabric with fleeting, changing and uncertain appearances like those of a living matter.

Here, no more lines on a black background, but a dozen flat surfaces of rectangular perimeter that move in the beam of several light sources.

Lines all in motion, curves and volutes....

Note that the pink lines of the first forty-five seconds are the image of a single deformation of a unique 3d object, viewed successively from six different angles; the resulting aspect is quite different from one angle of view to the other.

Animation softwares make it possible to simulate a light radiation.  But this effect can also help animate shapes and colors:

The arrangement of rigid geometric elements is added here to the effects of light, 

The geometric elements are now a light source, in a dark environment:
