Los Angeles California USA Calendrical Dial 593
A bronze-faced meridian arc dial 18 feet long, 13.5 feet high and 7 inch wide. Displays the meridian line and is inscribed with month and day markings, seasonal and lunar indicators and constellation figures. An overhead lens projects a solar image on the inscriptions. A large adjacent symbol is positioned to indicate which set of date markings is to be read from the meridian line. In a modern twist, photoelectric sensors embedded in the face of the arc are activated by the transiting spot of sunlight and send a signal to illuminate LED indicators on the 22 foot wide stainless steel ecliptic chart overhead, lighting up the stars of the constellation through which the sun is passing.
 
 
Queens New York USA Sculpture/Artwork Dial 592
A 6 foot diameter bronze sculpture reclined 50° (latitude is 40° 45' N) with slit gnomon and hour marks. Gift of Joan and Richard Scheuer in 2000. More sculpture than sundial, it does have some hour marks but reclines and appears to be out-of-plane.
