       | Sorry to be pedantic. For people just discovering art from the
       | early 20th century period, this fun project doesn't generate
       | Cubist-style art. Cubism was a completely different genre. While
       | Mondrian was inspired by Cubism in his earlier period, the art we
       | think of when we think of Mondrian isn't Cubism by a long shot.
       | Here's a good example of Cubism, Picasso's Girl with Mandolin:

       | 
       | And a side note. We nerds think we can generate Mondrians at
       | will. Here's a "typical" Mondrian (he had many sub styles):

       | 
       | There's even a programming language named Piet ostensibly
       | designed to let you generate Mondrians. It has been featured here
       | on HN:

       | 
       | Notice the samples don't look anything like an actual Mondrian.

         | originals were, and it was very difficult to generate something
         | that actually looked like a Mondrian.
         | 
         | I really ought to find that article again.
