This originally started as Setuini's "File View Launcher," but evolved into what I have now. Credit for the inspiration and foundation of what would become this skin goes to him.

TL;DR: This might not work at all
When an application is open, the icons are in color and their alpha is at 100%.
When an application is closed the icons go to greyscale and the alpha is around 75%.
When you roll over an icon with your mouse pointer, it goes to greyscale and the colors invert.

To set it up install the .rmskin file provided then go to the skins folder (e.g. "..\Documents\Rainmeter\Skins\Simple Dock\@Resources"). In the "@Resources\Launcher" folder place 14 shortcuts of your liking. If you want to use your own icons I've left an "icons" folder for you to place them in (this is completely optional). To change your icons image all you have to do is right click your shortcut file and click "Properties", then you click on the "Change Icon" button near the bottom. In the window that pops up you can click "Browse" and navigate to where you placed your custom icons and select the one you want to use for that shortcut.
Once you've done that launch the skin and it should set itself up. If something goes wrong post here and I'll see if I can help you figure out what's going wrong.
