Steam columns! Brilliant idea! Thank you.

BTW the background moutains -are- cones :) I'll stick a heightfield in there 
later when I'm happy with the foreground.

Thanks for all those comments, there's some good ideas in there. And 
regarding the underwater bit, I really don't want to lose the cutaway, it's 
what makes this image unusual, but you're right about caustics and render 
times. We shall see...
