Ah, yes, boobah you may be spot on.

A close review of the video reveals that he says " a review of all three applications which are open ". He is not opening three windows, he is just viewing the windows he has already opened.

W7 does this trick using Aero Flip 3D Use windows key/Tab to view them. Their is a freeware program which will
make the windows show flat on the screen but I do not have the address, sorry.

Hope this helps,

Aero Flip 3D shows all open windows stacked, like a deck of cards, the macro display (in the vid) open windows are arrayed in rows of smaller windows.

Welcome to Seven forums BTW. I don't see it as a Windows Snap feature, would be nice though.

You can snap with WIN+left arrow or WIN+right arrow

You can also just push one button on the keyboard to see everything that is open. Two over from the right side of space bar.
