| Q16: | What are plasma clouds? |
| A16: | They are a Fractint fractal and are similar to fractal mountains. |
Instead of a 2-d table of heights, the result is a 2-d table of intensities. |
They are formed by repeatedly subdividing squares. |
Robert Cahalan has fractal information about Earth's Clouds including how |
they differ from plasma clouds. |

Also some plasma-based fractals clouds by John Walker are available. |

The Center for the Computation and Visualization of Geometric Structures |
also has some fractal clouds. |
