Suzanne’s Brain
Pure entry, Cycles render, 64 samples & compositor denoising in 2.90.0 beta. Composition is Rule of Thirds, 3x5 aspect ratio, orthographic camera. Uses Extra Objects (Gears) and BoltFactory, two of Blender’s included Addons. Thing I did for this that I’ve never done before: It was gonna be volumetric steam, which didn’t work out. Lets see . . . I’m pretty sure I’ve never put this many gears in anything before! And I modeled a round-back eyeball that roughly matched Suzanne’s eye.
