Digital Funnel (with .blend file)

So here’s animated gif I did a couple days ago. It is procedural animation, done with sverchok addon. I’m attaching .blend file with, as full as I could, commented sverchok node-tree. Note, that in the gif render was changed a bit by post-effects, so raw render is a bit different.

File using HDR image from HDRi pack by zbyg 3 ( (packed in the file)

File was saved in blender 2.79-RC, and you need installed sverchok addon as well!
