It seems to "judder" or something when you're not on its tab. Which adds some variety, the one I linked above just went into a rather upbeat mode but has since, sadly settled down into Samsung Alarm Clock Mode.
EDIT: Another few well placed cubes and upbeat mode once again:

A good tip is to go on Facebook and just open a picture, click away so it goes to the main page then click a new image to load up. It makes it judder a bit, like a re-re-re-remix.
