Came across this time lapse video about the page layout process :)
To quote the author (Matt Willey):
This is a time lapse video of what goes into the process of page design. All of the permutations are quite interesting. Clients should take a look at this and understand that while we do move things around a page and send them a few versions, we move stuff around on the screen and in our heads about 100x more. In actuality, the client is seeing version 200+ by the time they see version 1.
