This confusing picture illustrates how 3D Rooms scenes might be incorporated into Pattern Combos.  The Background has been filled with a Single View Tunnel scene.  Then a Dual Views Tunnel (rotated) image was set into a hexagonal Area.  A diamond shaped Area holds another Dual Views Tunnel scene with contrasting Bubbles.  Finally, a Single View Tunnel fills an oval Area, with Bubbles matching the outer diamond.
