i had no idea mac could arrange icons on your desktop in a neat and orderly fashion (but i should have)! and while my desktop isn't always as messy as the first pic shown (it sure can get that way when i'm busy). you can arrange your desktop icons by name, date modified, date created, size, kind or label (awesome). just click on your desktop and go to "view" at the top menu. then click on "show view options" at the bottom of the drop down menu. click on your preference of icon order and voila--desktop looks neat and organized.
