Just to clarify and avoid any confusion. The word Screensaver is generally used for describing "a computer program that blanks the screen or fills it with moving images or patterns when the computer is not in use" more info here: https://en.wikipedia.org/wiki/Screensaver
While wallpapers are usually describing the background image of the main screen on a computer(and with more and more mobile usage it also applies to the start screen of such mobile devices).
Anyway... i like that first one. It's a thinker :P
