Asperitas
Asperitias clouds aren't officially a cloud type yet. The class was proposed in 2009.
This picture was taken in New Zeland. New Zeland is one of the most picturesque places on the planet. I've never been there but I would like to go.
Notice how organic the clouds look. It's almost like they want to be stroked. You can't help but wonder what would happen if you could.
