Poking through the window is just a matter of the separation of the left
and right images compared to the separation of the left and right apertures 
of the stereo mount.  If the image separation is greater than the aperture
separation, then the 3D image will lie farther away than the window.  Vice
versa, if the image separation is less than the aperture separation, the
3D image will lie closer to you than the window.
