[2020] could go in the title (or even [2017], looking at other comments in the thread in the following discussion link). There was also a discussion in 2021 of the same repository: https://news.ycombinator.com/item?id=26631995 https://news.ycombinator.com/item?id=26631995 (and that thread links to other discussions too) It's not quite the same, but I remember when I was first learning programming, I wrote a program that would generate a terrain heightmap, and do an isometric-style rendering using similar techniques. It was in QBasic, running on my middle school's 386-era DOS machines, and used graphics memory as its scratch space. Slow as heck, but I was fascinated with the output. It's one of the things that encouraged me to keep going with programming.
