The mandelbrot set, morphed into the shape of a heart!
A sphere, reflected between double mirrors.
Lava flowing!
This is a volumetric cloud, which changes color based directly on the number of photons that collide with it! However, this took FOREVER to render, which is why I had to heavily use the openAI denoising on it, and put a GIMP oilify filter on it.
This is another volumetric cloud, where the color is dependent on the density. A great way to add highlights!
