The below image is from a project called "Volumetric Redundancies", by artist JK Keller. In his words:

"This is a program I wrote that reads a source text and looks for words that are used repeatedly. The more the word is used, the larger its cube gets. Red cubes are words that are not unique, blue cubes are. The size of the rings is determined by the size of the paragraphs."
