Post-modernism is the remixing of previous cultural contents and forms within a given media or cultural form. Artists/designers look at past work and reinvent the already invented. When you hear the word "remix" it is often firstly associated with music. Drum music has evolved and changed into the new genres of dubstep and drum and bass. But today this new remix culture is seen in architecture, fashion, music, design and art.
An example of a remixed culture is the "Op Art" movement. Op Art is flat, static and two-dimensional, however it often appears to the human eye to be moving due to its precise, mathematically-based composition. This art creates a sort of visual tension, in the viewer's mind, that gives works the illusion of movement. The name Op Art, coming from "optical illusion". The characteristics of the style are geometrical, non-representational, perspective, juxtaposition of colour and positive and negative spaces.
Op art as might be thought is not derived from Pop Art, it is derived from the constructivist practices of the Bauhaus. This German school, founded by Walter Gropius, taught the relationship of form and function, analysis and rationality. Students were taught to focus on the overall design, or entire composition, in order to present unified works.
The above image is by Victor Vasarely, "His experiments transformed the flat surface into a world of unending possibilities, way before the advent of computers, making an era in the history of art". The image was created when light passes from one transparent medium to another, it bends. Light rays change direction as they go from air into the glass, and they change direction again when they exit the glass spheres and enter air.
