What they are doing has clear overlap with what we've seen in the demoscene. On a technical point of view, they generate all meshes and textures from formulas, using the same kinds of algorithms. See for example some 64kB demos that have landscapes / nature: - Paradise by Rgba, 2004 https://www.pouet.net/prod.php?which=12821 https://www.pouet.net/prod.php?which=12821 - Gaia Machina by Approximate, 2012 (https://www.pouet.net/prod.php?which=59107 https://www.pouet.net/prod.php?which=59107) - Turtles all the way down by Brain Control, 2013 (https://www.pouet.net/prod.php?which=61204 https://www.pouet.net/prod.php?which=61204) Of course, it's not exactly the same, the demoscene tends to focus on a few carefully crafted scenes and do everything in real-time (with up to 30s of precalc), but I think there's a lot of similarity.
