I see a Inigo Quilez link, I upvote! He's one of those incredible artist-engineer out there always pushing boundaries further and sharing his ideas and techniques publicly. If you have some time today, watch a few of his videos on his youtube channel, it's incredible to see his creation process in action: [LINK] For example, "Painting a character with maths" is mind-blowing and packed with SO MUCH educative content: [VIDEO]
