  64.       Solid Noise is a great texture maker. Note that this noise is
  65.       always gray, even if you applied it to a very colorful image (it
  66.       doesn't matter what the original image looks like -- this filter
  67.       completely overwrites any existing background in the layer it is
  68.       applied to). This is also a good tool
  69.       for creating displacement maps for the 
  70.       
  71.       plug-in or for the      
  72.       
  73.       plug-in. With the "turbulence" setting active, the results look 
  74.       quite a bit like real clouds. An example is shown
  75.       below.

  106.             If you check this, you'll get very interesting effects,
  107.             often something that looks much like oil on water, or
  108.             clouds of smoke, or living tissue, or a Rorschach blot.

  116.             This controls the amount of detail in the noise
  117.             texture. Higher values give a higher level of detail, and
  118.             the noise seems to be made of spray or small particles,
  119.             which makes it feel hard. A low value makes it more soft
  120.             and cloudy.

  128.             If you check Tileable, you'll get a noise which can be
  129.             used as tiles. For example, you can use it as a background
  130.             in an HTML page, and the tile edges will be joined
  131.             seamlessly.
