Hm, difficult to consider from far away.

This is not an analemmatical sundial. It's just a sundial which shows the 
mean noon by the aid of the eight-shaped analemma. An analemmatical 
sundial gives the apparent time by means of the azimuth of the sun. 
Because the azimuth does not clearly give the apparent time, the shadow 
caster has to be moved in a definite way.
