"Starry Night" Smoke Animation

This is a 3d smoke simulation that I was working on in SideFX Houdini to sharpen my smoke skills.

The simulation starts as a "Starry Night" colored box of smoke that is moved depending on the color of each point in space. Also, the density of the smoke is tied to the color of each point in space.

There is some light flickering in the render, but it is a test and I am not going to lose sleep over it! :) I also retimed the simulation slightly so that the image is more visible at the beginning. Enjoy!
