I know it's not really the right place for this, but I'm too lazy to direct 
you to p.b.s-f, so see attachment :)

it's used like this:

fastclouds(Sun_Location, Cast, Fluffyness, Translate, SkyScale, CloudScale, 
MinimalTransparency, Sun_Color, Ambient)

(skyscale is multiplied by 500 internally, don't ask me why :))

you can change the pattern used for the clouds by declaring CloudForm (which 
is a pigment)

It only creates the clouds, not the sky, so you should add your own sky. 
The full code for the clouds used in these images is:

//--start code--//
#include "fastclouds.inc"
fastclouds(<600,750,-500>*1000,.455,.1,1000,10,.05,0,<1.5,1.3,1.1>,1)
fog {
  fog_type 2
  distance 75
  color rgb <213,205,194>/255
  transmit 0
  fog_offset -1
  fog_alt 2
}

sky_sphere {
 pigment {
  planar
  color_map {
   [0 rgb <22,44,68>/255]
   [.5 rgb <88,120,179>/255]
   [1 rgb <213,205,194>/255]
  }
 }
}
//--end code--//

cu!
