Since @johncarlosbaez posted about tetrahelices (https://en.wikipedia.org/wiki/Boerdijk%E2%80%93Coxeter_helix) the other day, I thought I'd share something I recently made on Shadertoy: https://www.shadertoy.com/view/sfBXDR . If you look at the implementation closely, I generate the points of the tetrahelix through a recursion relation, instead of using the trig formulae in the wiki page. #math
