This shader is a proof of concept to see if I could create a "typical" Shadertoy shader, i.e., a shader that renders a non-trivial animated 3D scene using a ray tracer instead of the commonly used raymarching techniques.

I found this article: http://www.ams.org/notices/200304/fea-escher.pdf describing the transformation used by Escher in the droste-picture: de prentententoonstelling (the picture gallery). The source is a mess atm - I will clean up later.

Loopable variant of https://oneshader.net/shader/77061bc5ed by using the iLoop uniform vs iTime. The iLoop uniform will loop from 0-1 every 4 seconds.

A simple shader that demonstrates how you can use adjustable uniforms in your shader.

Experiment to generate some well-known textures (from the first-person shooter video game developed by id Software) in a textureless shader.

I wanted to create an organic-looking SDF scene in a single, fully procedural, fragment shader. The scene is modelled for this specific camera viewpoint and lighting setup. Please change AA (line 24) to 1 if this shader is running slow.

Based on matrix - 255 char by FabriceNeyret2: https://www.shadertoy.com/view/4tlXR4 compacting to 2-tweets patriciogv's Matrix shader https://www.shadertoy.com/view/MlfXzN ( 819 -> 255 chars ) But first go see patriciogv's comments and readable sources :-D
