Thought i'd point this article
out for people interested in creating abstract art. It's some new research that talks about how to use repeated asymmetric patterns to generate the illusion of movement in a static image. Artists such as Bridget Riley have created entire bodies of work
based on working with visual illusions in their art. Illusions like this can tell you a lot about how the brain's visual processing works. And they also point out fun techniques you could use in your own artwork if you're interested in incorporating a visual sensation of movement into a static image.
