This is one of my menus showing movies I am currently designing. The top twelve icons open a sub-menu as they are all series of movies or trilogies and I didn't want to have to look at eight or so icons for the same theme such as James Bond. As you can see I have one icon showing the three Bonds that feature within it. Moonlighting goes to a folder that has multiple episodes in it. I have one for Star Trek on another menu that goes to yet another sub-menu with 90+ files in. I find doing it this way it is easier to catalogue hundreds of files so that it is intuitively simple to find what I want, without scouring multiple images which may distract from a quick visual search.
