WEB2DNA is a fun little application that interprets the semantic structure of your web site into a representation of human DNA.
“Basically a semantically rich site will appear brighter than one with messy old-style code.
You can also determine the richness of text on a site. A site the focuses on (text) content is one where the DNA patterns is large (filling many containers), but contains a lot of empty spaces between the lines (empty space is the individual words).”
