There are many good examples of Cubism on the site link above.

Once again, I am using the web sites: Spoon Graphics and Tuts Plus to show you some amazing tutorials and examples of how to create Poly Art, (originally known as Cubism, but the portrait to the left that is taken from the Geometric Poly Portrait Tutorial below, is a modern riff off of Cubism that also combines the work of Henri Matisse.) To understand Cubism please research Pablo Picasso, George Braque, and Marcel Duchamp's Nude Descending A Stair Case as well as watch this video: Understanding Cubism Video.

The article below was taken from this website link: ( http://thingsworthdescribing.com/2013/05/16/portrait-of-pablo-picasso-by-juan-gris-1912/,) I would have just made a link to it, but as it shows a "not secure" warning in my web-browser, so I am just pasting the content of the article below, (I just want to make sure that the original author is credited):

A painter paints another painter in this picture, a man in blue holding a palette of colors. And since this is Picasso, it’s done in a style based off of his own. His figure is disjointed and geometricized, turned into shining cubes of color that hold pieces of a nose here and an ear there. It’s like looking at a realistic work by Picasso through an organized kaleidoscope.
Juan Gris was a Spanish painter and sculptor who met Picasso in France after moving to Paris in 1906. Gris regarded Picasso as a teacher, but Gertrude Stein wrote “Juan Gris was the only person whom Picasso wished away.”
