Nice day for some NEPHELOCOCCYGIA?

What's "the word I'm thinking of"? Today it's....

NEPHELOCOCCYGIA (noun) [nef-el-o-kok-sij’-ia]

Cloud gazing; the act of looking for and finding shapes in clouds; also, when capitalized, the name of "Cloud-Cuckoo-Land" in Aristophanes’ The Birds

"Terrence spent Saturday prostrate in the yard and in nephelococcygia, finding inspiration in the thunderheads."

I remember seeing a lot of things in clouds as a kid: faces, cities, fabulous beasts. I can’t do that anymore, which is sad. Now I just see water vapor, though I still can’t quite believe, sometimes, that I couldn’t sit on one of those diaphanous thrones if I could just get up there. (TWITO, page 95)
