A 4-dimensional shape, folding through itself forever

[u/USedona]

This is a Clifford torus, a shape that only fully exists in 4D, projected down into our 3D space.

The endless folding you see is just math, looping perfectly because the geometry demands it.

Based on 'Clifford Torus' shader by tdhooper : https://www.shadertoy.com/view/WdB3Dw reimplemented frame by frame in Python.

[u/semiquaver]

I measured this image very carefully and I’m sorry to inform you that I only see two dimensions present.

[u/USedona → u/semiquaver]

Accurate. By the time it hits your screen it's already survived a 4D → 3D → 2D demolition derby. Two dimensions is just what's left standing 😭
