A few weeks ago I checked out what Google's Gmail web email application looked like without any stylesheets enabled. I did this by disabling them using the Web Developer toolbar for Mozilla Firefox. I have just checked and it still does a similar thing, though before all the small boxes were full, they are empty by default, but are triggered by some of the links.
It shows three seperate boxes with "Compose", "Inbox" and "Starred" sections. Another box below has "Loading..." which appears before the boxes have content.
