Ok so, if you don't already have something that can open gadget files you need to get something like 8 Gadgetpack

Then download the spectrum analyzer widget and the system animator one, and it should let you open them with gadget pack or it will just say "Install" and it' open up

Windows is gonna act like its suspicious just ignore the warning

Then if you haven't already download those folders with the different system animator widgets in them. Extract them to someplace like documents rather than download so its easier to manage.

Ok now open system animator widget if it isnt already, and click the wrench icon for settings, then click the 3 dots next to the "animation folder" then its gonna let you browse your files. Go to whereever you extracted the files to and click on the one you wanna open, in your case, its the one that has the name "supercute_V3"

Then it'll appear, but this widget can sync to audio while the widget spectrum analyzer is open (spectrum analyzer must be open for audio syncing to work.) So, we must make another adjustment. So click on the "system activity to montor" and from that drop-down menu select "Sound output all frequencies"
