Okay, so the faves got me motivated to finish the matching wallpaper to the activation screen. Again this was loads of fun to do and I like to share it so everyone else can have it as well. Credits be at the bottom.
Downloaded Image Demensions are 1920x1080 Which means if it's too big for your screen, you can always.... right-click the desktop/personalize/click on desktop background/ and then there's a drop down menu thing so click that/then fit screen. (Not sure how to do that on the Mac....this is just basic Win 7 instructions.)
