Just designed my own Apple Cinema Display HD icon. I'm actually designing my own graphic design website, so I made this icon to use for one of the hardware I use. This icon officially took me the shortest time to make
out of all my icons thus far. It's pretty much 70% in the way the gradients are applied. Enjoy!
----- UPDATE: ------
A lot of people asked me if they could customize the desktop background for the screen, so I provided the PSD to do so
. I also created, for ease of use, the exact area where the desktop screenshot should go as a layer mask, so to activate it do these steps:
Place your desktop screenshot or a wallpaper, and if it doesn't fit properly, go to menubar (OS X), or File (Windows) > Select > Load Selection. From the drop down menu, select "Desktop Screenshot Cut", and hit ok, and this will make an automatic selection around the area where the desktop goes. Then just hit delete on the keyboard, and it will delete the excess area on the desktop. This is much more useful if you just want to place a particular wallpaper of your choice on the desktop, rather than a full desktop with the dock, etc, because then it will already be a pre-defined resolution size (that you have to lower to 512). Enjoy!
Sorry about the re-download.
