Etienne Jacob is a software engineer in Paris, and he's also an artist. His creative coding renders moving images that are just pixels, but they are placed in such a way as to bend our minds. They illustrate the confluence of math and art. Jacob's gif are looped, so that they never end and are liable to mesmerize you into watching them over and over. The moving image above is titled Torus Curve, while below you see Sphere Wave.
