'Muzei' along with 'Muzei - Tumblr Photos' is the best thing to happen to my phone's background. I have tried so many other apps  but I never was satisfied with either their collection or the options to blur  darken and cycle wallpapers. Muzei  along with the relevant addons  does all this. Note to newbies: when you add a source  it can get confusing to find it. Just SWIPE LEFT. It doesn't matter that this app hasn't been updated for years  it's still the best!
