Part of Max Cooper and Tom Hodge’s Emergence project, Teotihuacan Part 2 is simple in concept and gorgeous in execution. Or at least as simple anything involving higher dimensions of space can be. Backed by Cooper and Hodge’s composition, the video rotates a four-dimensional object through three-dimensional space, represented on a two-dimensional monitor. From that (relatively) simple action, complex patterns emerge, getting increasingly intricate as the piece evolves. It’s utterly absorbing, but also soothing (probably because of the mostly ambient score) and almost hypnotic. Yes, it says something that it took a mathematician to create the code that made the video possible, but it makes sense, given that so much of modern math is about how complexity emerges from simple rules, and the beauty that can result.
