Plasma generates colorful clouds, which can be used for
textures. You control the turbulence in the plasma cloud with
the Turbulence slide.

All of the colors produced by Plasma are completely saturated.
Sometimes the strong colors may be distracting, and a more
interesting surface will appear when you desaturate the image
using
<span class="guimenuitem">Layer/Colors/Desaturate</span>.

<span class="guilabel">Random Seed</span> controls the randomization
element. The <span class="guibutton">Randomize</span> checkbutton will
set the seed using the hardware clock of the computer.
There is no reason to use anything else unless you want to

on a later occasion.

<p>
This parameter controls the complexity of the plasma.
High values give a hard feeling to the cloud (like an
abstract oil painting or mineral grains), low values
produce a softer cloud (like steam, mist or smoke). The
range is 0.1 to 7.0.
