first mondrian ... now picasso

The last time Google celebrated a painter's birthday I could see a connection. This time it's Picasso, but the connection is still unclear (barring the fact that he was a great painter, of course). Information Retrieval is one of the domains that Google derives a lot of its core from. One of the important books in this area is Information Retrieval: Data Structures and Algorithms by Bill Frakes and Ricardo Baeza-Yates. The book uses Piet Mondrian's Composition in Brown and Gray on its cover. I am convinced that this, among other things, motivated Google's Mondrian tribute. With Picasso, I can't remember any such reference. Of course, this could all be a vain geeky exercise in conjecture and association.
