Did you know that if in Windows 7 you grab the active window by the mouse cursor by the title and move it (window) left and right, like an eraser that erases a pencil, then the other open windows will be minimized and the active window will remain active?
If not, be sure to try :)
Well, so that this post was a bit more twiformate, under the cut, I prepared an exemplary hyphae animation.
who wants magic, do not go under the cut (although in principle it is already late)')

ps so that the gif is not much messed up the eyes of the last frame a delay of 10 seconds, after everything repeats.
pps with pleasure share the features of the seven you found.
upd: as suggested in the comments, this is Aero Shake, which everyone knows about.
upd2: fierce windovers, plus a topic, and then the fierce Linux users will now all think of it :)
upd3 is mourning for windows 7 lovers, all plus points are turned to the side and no one will know (who still does not know) that the seven is beautiful even in small things.
