A more serious attempt at using the Animation nodes Blender extension for procedural generation. The image is 100% procedural based on modulated noise; the poodle is just a hallucination of your brain. (Seriously though, if you can't see the poodle then good for you because you won't be able to unsee it.)

3D rendering. In the foreground, there is a sparse mesh made of small spheres connected by thin cylinders, all in green. In the background, slightly off-center, that mesh gets denser and forms a big sphere. The sphere is illuminated in yellow-white from the inside. A slightly twisted path leads from the bottom edge of the image into that sphere. The path is composed of triangle platforms, and illuminated by a long chain of glowing cylinders.
