In these dials, one stands on the appropriate point on a month scale and one's shadow falls on a hour point. These points are on a an ellipse, which is the projection of the equatorial circle onto the ground. By splitting the ellipse and splitting the month scale, it impossible to make a mean time dial

In Australia, there are a number of single analemmatic dials (or, as they called there, "dials of human involvement"). Here the normally straight month-marker line is replace by an analemma with the months marked along it. This method makes attractive dials - but theoretically they do not give mean time.
1996 : Beautiful analemmatic dial near the Beach at Torquay, Victoria, Australia.  It is a mosaic comprising more than 120,000 Italian glass Tesserae tiles. The mosaic represents the traditional dreaming stories of the indigenous Wathaurong people, with images of flora, fauna, marine environments, star constellations and local aboriginal stories
