Hi community!

In essence, there is a scene, rendered into two rendertargets, with some objects, whose layers toggled at rendering. And then, those render targets are mixed on a quad (simplex noise used).

Interesting. The black stuff looks like ferrofluid (although not as spiky as it is).

Well, yes, I tried to make it look similar to ferrofluid-like. The object is just a bunch of tetrahedra, that I made from `IcosahedronGeometry`. 🙂
