I think I got my info from the help file in on the unlimited version.
for his sky you have to position your camera in just the right spot to get the effect your right there.
They animate well but you have to move the hole fluid container in one direction to get a nice effect. The fluid system move around nicley inside The container so theres no need to have more then one . IMO
have fun.......
