Gnome 2 (actually, Compiz) had a very very similar feature. It was merely disabled by default. It was called "desktop wall". I /think/ it even was enabled by default at one point.
You'd strike a key combination, and you'd be transitioned from a single desktop view to seeing the whole desktop grid, in an animated style.
I found it quite nice at the time, although I didn't use it much.
Where I guess it differs, is that in Gnome 3 you see /just/ the apps you started, instead of all the desktops.
