You can click on the closet and pewdiepie will jump out of it, after that some shortcuts will show up. The figurines are shortcuts and the guitar, but you need to paste your program paths in the LeftMouseUpAction=["#"] of the skin by right clicking -> edit skin. The theme comes with a visualizer that is made with musicolor, but it uses a lot of ram so I suggest not using it.

The background of the theme is in the folder of the theme (documents/rainmeter/skins/pewdiepiecloset). Or you can download it here I used transparent taskbar in this screenshot.
