A source for over/under viewers and large format side by side viewers
see:
http://www.rmm3d.com/viewers/viewers.html

The over/unders work for up to 4" high views of any length. The other I
believe well take 8" wide views of any length if you want vertical pans.

For all of your stereo questions and links go to stereoscopy.com.
