An abstract animation using Blender 2.80 with Eevee ‘Principled Volume’ shader and a few point-light particles. The end merges seamlessly with the start so the video can be looped.
The effect is loosely based on the YouTube tutorial ‘Creating Nebulas in EEVEE (Blender 2.8)’ by Curtis Holt at https://www.youtube.com/watch?v=kYv3ZIlb_sU
Rendering took about 30 seconds per 1920x1080 frame. The video is 2000 frames long, so the total render took about a gazillion years - or at least it seemed like it at the time. On a related subject, if anybody has a spare super-computer lying around, Christmas is approaching and I would be very appreciative
