That happened on The Office.
I don't watch The Office so I wouldn't know. It's just something I do in class when the teacher lets the screensaver go.
I do that with my DVD screen when we have to pause- even more fun since it changes colors when it hits the walls
We used to do this after we'd watched a DVD in highschool and the screen saver had come on. The teachers never really cottoned on to why we sporadically got excited and cheered with enthusiasm throughout the class.
I'M NOT THE ONLY ONE!
For the screen savers that change color, I try to guess which color will come next.
