Simulated Clouds

Inspired by the breathtaking views I saw out the window of a recent flight, and the way the sun filters through clouds to create beautiful colours and effects, I found a program which cleverly simulates this. In this demo video however you can see how the beauty of a simulation is only a fraction of what can be seen in real life. I would like to try and create similar effects with other materials on a smaller scale however I suspect that the intensity of the light from the sun and the scale of natural views are what make them great.
