The various objects of the universe may be constant, at times, but their reciprocal relationships always vary. - Alexander Calder

To me the most important thing in composition is disparity. Thus black and white are the strong colors, with a spot of red to mark the other corner of a triangle which is by no means equilateral, isosceles, or right. To vary this still further use yellow, then, later, blue. Anything suggestive of symmetry is decidedly undesirable, except possibly where an approximate symmetry is used in a detail to enhance the inequality with the general scheme.

I started [in Paris, 1920's, making toys] right away, using wire as my main material as well as working with others like string, leather, fabric and wood. Wood combined with wire (with which I could make the heads, tails and feet of animals as well as articulating parts) was almost always my medium of choice. One friend of mine suggested that I should make bodies entirely of wire, and that is how I started to make what I called 'Wire Sculpture'. In Montparnasse, I became known as the 'King of Wire'.

What I mean is that the idea of detached bodies floating in space, of different sizes and densities, perhaps of different colors and temperatures, and surrounded and interlarded with wisps of gaseous condition, and some at rest, while others move in peculiar manners, seems to me the ideal source of form.
