Cubism, the Big Picture

I've put a PDF file on my website called "Cubism: The Big Picture", here. It's an essay I wrote last year on the origins of Cubism and its logic and rationale, focussing mainly on Picasso. It's just over 2000 words, about 10 pages. I will do it in html eventually, don't have time right now. The conclusion I came to was not what I've seen in standard sources such as Gombrich. Unfortunately I had to take out most of the images and put links instead. Comments would be great... and please do email me at folio@wow.net if the file gives any trouble to download or to open.
