Procedural Nebulae

I spent the entire day taking a first crack at starfield/nebula shaders. I couldn't be happier with the results! Below the output of a single shader that consists of thresholded pink noise (stars), and two turbulent-input multifractal perlin noise layers (nebula density/color).

Couple these results with a procedural planet, procedural terrain, and procedural sunset, and things will be starting to look pretty good for project A New Reality!
