This photo is of a analemmatic type of sundial in the front of the UPrep High School central building in Wedgwood Neighborhood. The design is described below. The sundial is an iron gray cylinder with stainless steel lettering, indicating the hour of the day along the sides. Stainless steel lettering also designate the lines for the winter equinox at the top, both solstices at the middle and summer equinox at the bottom. There is a handle at the bottom, about waist height, to move the gnomon so that the sunlight can strike its slit and fall on the correct hour of the day.

The sundial is oddly attractive, looking a bit like a welded futuristic rough idea of a robotic Dakek.
( The followin is from  https://sundials.org/index.php/sundial-registry/onedial/746) A unique, 10 foot tall, 2 foot diameter (base) tapered cylinder dial similar to a traditional shepherd's dial except that the cylinder orientation is fixed and the gnomon is rotated about the dial axis by the user to align with the sun. Time is read from the vertical hour and date lines. The dial is fabricated from bronze plate and is hollow. Lines are formed by individually cut hour and date line segments welded on from inside the cylinder. A lever at hand height is moved to rotate the gnomon to face the sun, providing a vertical shadow. A slit in the gnomon tip provides a more accurate sun spot on the dial face.

Went to check the analemmatic sundial at Uprep HS, and it works very well in winter! This is at high noon (the sun is still winter low)
