I did find one interesting thing about the clouds, that if you run 'polar coordinates' filter on them enough times, it turns into an ancient stone tablet depicting a battle between a giant robot and a giant lizard at the site of a nuclear blast.

There also appears to be a giant turtle and a giant squid. They might be flying.

LOL pwned.
