Hi, John, Since you like the Duixons sundial, I put on two more pictures of it. One from another angle and may give you more idea about its 3D structure. The other is the plaque on the ground in front of the dial. It is about the designer's name and the date it was made. See http://photo.xuite.net/_my/b_6_5?ab_id=1477368&p=134 and the one next to it.
