Hi, dear members: A new glass sundial, close to horizontal type, but inclined due west by 10 degrees, is going to be installed in JiaYi, Taiwan next month. The dial will be put up to fit in an empty space, 6 meter high from the ground, of a landmark structure, which is shown in the attached diagram. The yellow oval-shaped area in the diagram is the place the dial will be installed. To view the shadow of the gnomon on the glass dial plate, one has to be under it and look upward to his top. To this point, it is unlike those normal window dials, which one just needs to look front or with an angle not too high.
This is what beyong my knowledge: is there any dial of this kind (glass and look upward to one's top) around already? Please help. Best regards, ChiLian Chiu N25, E125, Hsinchu, Taiwan
