Yes H, and I see the " Bad Astronomy " blogger, Phil Blatt(?) picked up by Slate also posts about clouds. CAS needs to be introduced to him.
The Atmosphere is a good metaphor for our imaginations. It holds stuff unseen until conditions are right, and then ideas and thoughts like cloud, condense out of nowhere and manifest themselves to the prevailing winds and light. Rod Serling began every one of his Twilight Zone episodes with, " Between sight and sound there is a place." Indeed, its called a cloud.
