Created using a particle system of metaballs with just touching field strengths. Meshed, decimated heavily, wrote a python script to subdivide all the separate objects and spherify them a little. nice SSS material and depth of field camera. glowing filament lights were created by tracing the paths of a turbulent particle system movement then an emissive material.
Part of my learning Blender series. Rendered with the help of Sheepit renderfarm.
