There is something about clouds, a sort of Rorschach Test or creativity prompt in the sky. In text, I use randomly chosen words to force connections and make ideas. Clouds do it for me in image form.

I must admit I prefer jagged-edged clouds that could be animal shapes. I don't see animals here.I like Lacy's cloud as one to build a castle on top of and Boutwell's could be a sky-highway. Maybe the boundary between two two magicians in battle.
