Oakland California USA Projection Dial 613
One of Bill Gottesman's unique-design Renaissance dials of cast and structural bronze with a 27 inch diameter helix with a celestial-north aligned axis. Time is told by a focused beam of light that moves around the helix throughout the day. The light beam is reflected from a long cylindrical unsilvered mirror in a structure that supports the helix. A sliding time scale within the helix can be adjusted for EOT and DST and includes longitude correction. Once this scale is adjusted for date, the dial shows civil, or clock, time. The dial base is cast bronze allowing adjustment for latitude and placed on a concrete pedestal.

An 18 inch octagonal horizontal dial of cast bronze. The dial face includes hour lines with ten minute marks and Roman numerals. The dial is on an octagonal polished granite pedestal.

Lexington Kentucky USA Horizontal Dial 606
A 14 foot diameter horizontal dial of granite, marble and limestone with shrubbery delineation in the center of a cul de sac street.

Dial face includes two 6 foot diameter inlaid mosaic maps of the Western and Eastern Hemispheres. The gnomon is a truncated three-sided equilateral pyramid that inclines to the north so that the northern corner is vertical. Two bronze plaques give instructions for reading and equation of time correction. Seen from above, the overall design incorporates a Yin Yang symbol appropriate for this elementary school specializing in teaching Chinese language and culture.

Toronto Ontario Canada Horizontal Dial 596
A 210 cm diameter horizontal dial of blue granite with a 56 cm high stainless steel gnomon. In addition to showing local time, the declination line that touches the base of the gnomon traces the path of the shadow on June 23 (date of the 1985 Air India terrorist-bomb air crash) and also marks solar noon at the crash site near Akahista, Ireland where there is a similar memorial sundial. Stones forming the pedestal represent all of the Provinces and territories of Canada, and the countries of India, Ireland, Japan and the United States of America.
 
 
Delaware Ohio USA Armillary Dial 595
A 24 inch diameter stainless steel armillary dial with equator, meridian and horizon rings. The armillary includes compass points and zodiacal symbols. The dial sits atop a 6 foot tall architectural sculpture of four two-columned arches also made of formed and welded stainless steel sheet with a random polished pattern creating dark and bright areas that change as the sun moves across the work. The armillary is held by fingers of a sculpted hand, representative of works by the designer, Alvin Sher, and symbolizing mankind, creativity, knowledge, peace and greeting as well as identity among many other human meanings. The dial sits atop a six foot tall stainless steel architectural sculpture with four pairs of columns with a supporting arch between each pair. The entire sculpture is made of textured and welded sheet up to 3/16 inch thick.
 
 
Louisa Virginia USA Cylindrical Dial 594
An internal cylindrical dial built in a 16 foot diameter, 48 foot tall farm silo now located on a public golf course. The rim of the open top of the silo provides an elliptical shadow line on the inner wall of the silo. This is marked out with red hour lines and black date lines using the low point of the shadow on the wall as the time marker. The artwork has "three panels representing the continuity of man's perceptions of space: past, present, and future. In an abstract sense, the sundial represents the scientific, emotional, and philosophical struggles and triumphs of mankind." Contact Tanyard Country Club Golf Pro Shop at 540-967-1889 to ensure the silo door is open.
 
 
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.
