Show HN: Rotating torus in terminal (but with kitty graphics protocol)

Hi HN, I'm taking Computer Graphics @ Stanford this summer and wanted to express some very simple concepts I had in mind. That's why I wrote a rotating torus in C. Going from writing a ray-tracer that works in Blender to pure C with no dependencies feels relaxing. Wanted to try Kitty Graphics Protocol on the way, rendering images in terminal felt cool. Open to comments and suggestions.
