At first glance I wasn't too keen on the name. I guess it depends on how you define the word Icon.
The computer definition doesn't really work - A picture on a screen that represents a specific file, directory, window, option, or program.
Far more relevant is this one - One who is the object of great attention and devotion; an idol: For example a pop icon, or movie icon.
So, for the purpose of development, you would need to do a site that focuses on desktop or mobile phone wallpapers of Famous people, such as Pop Icons.
Could work great as a developed site, undeveloped you might get mid $xx for this one.
Good Luck
