Ever since developers were turned loose on the new Muzei live wallpaper, we've been seeing really cool extensions. A lot of extensions, actually. So many that it can be hard to choose which one to use. Now you don't have to agonize over the decision – MultiMuze cycles through them all automatically.
MultiMuze is accessed through Muzei just like any other extension. Just open its individual settings to tweak the performance. You can enable and disable each source and choose how often it moves on to the next one. This extension won't override the refresh settings of other sources, so no need to worry about the sources refreshing too quickly or eating up mobile data.
Like all the other Muzei extensions out there, this one is free.
