Interior Window dividing two rooms

I was watching HGTV today and one house had a window up high in a bedroom separating it from another room (unsure as to what kind of room).  I thought what a great place to put a leaded glass window.  It would add a nice touch to both rooms.  I did one like that in a house in Anchorage, Alaska where the window separated a bedroom from a walkway at the top of stairs.  It was up high enough so no one could see in.
How do I get in touch with these designers to show them what can be done in a space like that?
