Have you even tried Gnome 3? There really are no "3D" effects. Just because it's using advanced features of your video card doesn't make it 3D.
The closest thing you'll see is that when you switch from a "Show me all my windows in an overlay" view, the windows will shrink/grow into place, which *in that tiny point of time* helps associate the zoomed-out tile with the window that's there.
Unity has some other plugins for 3D effects if you really want them, but they're hidden away because they're more like tech demos than real features.
