Hi Luke: >Karl Schwarzinger's very nicely designed Analemmatic Sundial in Tyrol >(URL below) integrates both a raised and slopping platform to add some >compensation for height limitations in a larger sized dial. > A great way to solve the gnomon height problem with analemmatics. Just build a platform marked with dates on which the user stands. This also serves a bench for sitting and the attractive visual component that Sara mentioned.
Even so, I think I will go with Patrick and Henry's suggestion of a horizontal dial with human gnomon. Thanks for the Austrian sundial site. All the dials pictured there are beautiful (I especially liked "27) John
