Fernand Léger's film, 'Ballet Mecanique' is the result of the desire for a picture in motion. - Alexander Calder

In the Spring of 1926 I made some toy animals of curtain rods, broom handles, etc., and wire. Later, a few dolls, which I animated.... In the Winter of 1927–1928 I made some more toys for a friend to take home as gifts, and having shown them to De Creeft a Spanish sculptor with a very acute sense of humor, I was urged by him to make some more toys and to expose them at the . I did this and then began to make more elaborate toys, with articulation, in which the movements got more and more realistic, always adhering to the same basic materials. In this way I have developed quite an elaborate circus of which animation is one of the chief characteristics....

My entrance into the field of abstract art came about as the result of a visit to the studio of Piet Mondrian in Paris in 1930. I was particularly impressed by some rectangles of color he had tacked on his wall in a pattern after his nature. I told him I would like to make them [Mondrian's flat painting] oscillate, he objected. I went home and tried to paint abstractly - but in two weeks I was back again among plastic materials.

It was more or less directly as a result of my visit to Piet Mondrian’s studio in 1930, and the sight of all his rectangles of color deployed on the wall, that my first work in the abstract was based on the concept of stellar relationships. Since then there have been variations from this theme, but I always seem to come back to it, in some form or other. For though the lightness of a pierced or serrated solid or surface is extremely interesting the still greater lack of weight of deployed nuclei is much more so.
