muzei - by the maker of DashClock!
Roman Nurik, the maker of DashClock, has done it again:
What's so great about it? Well, it's essentially a live wallpaper that cycles through famous and not so famous paintings; The interface is really good-looking (images below) and Roman has again made the app expandable so extensions have been popping up all over Google Play in the past couple of days (500px, Reddit, Nat Geo etc extensions that add photos from those sources are already in the Play Store). There are other apps that cycle through lovely backgrounds (FreshBacks is an especially good one) but the flexibility of muzei really puts it in a league of its own. It still won't make me remove my lovely Mountains Now LWP for the moment but perhaps sometime in the future?
