  Well, being based on planes, it works better for viewing directions not 
much paralel to the planes.

  Not tried it, but sounds like a fine solution from Zeger description, and 
seing the clouds on his images, I think it can be appropiated for your 
scene. Being spheres instead of planes, the point of view seems not a big 
problem. Definitely, I must try it someday...

  Thanks, I tried to make the design simple but also not too boring.
