For this entry I took inspiration from the challenge by @renderweekly - using two of my designs: the Trefoil Knot and the 3D triangular tessellation.

Since the basic designs were already made - I just altered some of the parameters - I took the opportunity to experiment with the materials and workflow of Blender 2.8. For now I ended up using Cycles but I'm planning to use Eevee more and more as the fast rendering times will allow to create short animations.
