What the Hacker News discussion says — and what it does not
Discussion focus
Across the sampled HN recommendations, people specifically point to Builds a 3D scene from a formula step by step and Mind-blowing math art with live coding.
A recorded perspective
The recorded HN source is “This was a mind blowing example of math and art from last year” — a useful perspective from kn8a in 2021-01, rather than a claim that every Hacker News reader agrees.
Evidence boundary
Alongside recommendations, the export retains a reference mention from t8y (2022-02): “people appreciate that it's a shader, even people that are not into programming” This is context, not proof; use the linked discussion to inspect the original thread.
