Clouds at sea - you may recall, if you click on the picture it will show a much larger version.

I have been looking at an artifact called the nltk (natural language toolkit). It has all sort of wonderful tools for analyzing texts. This is a dispersion plot for some words in Vol I of Ruskin's Modern Painters. I think it speaks for itself (I'll have to read it again one of these days and see why there is so much seeing, but no light a third of the way into the book).
