I noticed a couple days ago that the wave live wallpaper now supports Google TV. It provides an option within the app to set it as a screensaver, which seems to trigger a hidden menu for screensaver settings. I notice if I go there, any other live wallpaper that supports screensaver can be set to (i.e. pixel fleet, project M, I'm experimenting with others.)

The thing is, there is no option on my Google TV chromecast settings to get to that menu. I have to go through the Wave LWP app. Is there a shortcut app to get there that I (and anyone else wanting to experiment with this) can use instead?

Also, in other news, you can use animated screensavers on Android TV if you can sideload live wallpapers that have screensaver support. (I haven' tested them all.)

Edit: Works with My 3D Fish 2, and the Xscreensaver app from fdroid.
