Clouds are cool. They're also good for turbulence when traveling through fluids, or have random objects block light, which is useful to have if I want to have a general AI/robotics prototyping system with different power sources (like sunlight, wood, etc.) Also, that same algorithm is good for generating landscapes.

3D Brownian motion on simplex noise is hard though, and it looks cube-y for some reason. Why does it look cube-y?
