Tilt parallax
The wallpaper shifts slightly as the phone moves.
Quality
Live wallpapers are an OS feature, and no browser on any platform can install one — this page previews the effect, the Android app runs it. In the app, motion stops completely whenever the screen is off or another app is in front: nothing is drawn and the accelerometer is released.
With parallax off and no effect there is nothing moving — set it as a normal wallpaper instead, which costs no battery at all.
