Cackle: PKM Dolly w/ Anim

Renders of the Pseudo-Kleinian Menger fractal. I've been wanting to do a path traced version of this one for a while now, but I needed to add direct lighting to Cackle first. With a GTX 1070, each frame takes ~25 min. to render at 16 samples/pixel and 3 bounces. Nuke was used for some color correction.
