Yeah that's a really good idea Will, would like to see that being worked out.
Currently I have one render cooking (going to post it on this forum within 6 - 8 hours) and I'm at work, so I can't experiment for now.
I like the first one the most, but in the last one the rainbow effect really adds something. I like the clouds, they look a bit surrealistic (
), but they are very cool!
