It’s like a ballet performance of those geometric shapes. These shapes are of primary and high saturation colors like red yellow blue and green, setting against a black background with two expanding circles. They move along the music and change the forms while the emotion changes. When the music grows slower and more melodic the small diamond shapes are swimming together like a group of fish. When there’s a big loud sound and the emotion get stronger, the shapes will expand and even seems to get out of the screen.
In my research, I found out that Fischinger was experimenting the colored liquids and three-dimensional modeling materials. So, I guess he got inspirations from those colored liquids and materials. The 3d modeling materials are solid, like the triangles and squares in the film, and the movement are like the flexible color liquids dancing with the rhythm.
These geometric ballet performance makes me relate to the Bauhaus stage performance I learned in another class. And they are around the same period of time where the industrial revolution influences the world a lot, including art. So, I guess there’s where the mechanical shapes and accurately calculated movement comes from.
