I Tried Turning Games Into Text

Acerola's video on turning games into text, rendering a game's image as ASCII characters with a post-processing shader. He uses edge detection to pick characters that follow the shapes in the scene.

HN people recommend it as a nice overview of doing ASCII style in a shader, and as the reference for edge-detected oriented characters.
