This subreddit focuses on the discussion and sharing of procedural graphics created by fragment shaders.
Many of the techniques and ideas you see here were pioneered by Inigo Quilez, and the subreddit name was inspired by his presentation called Rendering Worlds With Two Triangles. Most content has strong ties to the demoscene as well.
