This is a polar sundial using a rod gnomon.  Using a template from Shadows software,  the dial is constructed of handmade ceramic tiles mounted on an aluminum bar frame, tilted at 38.6 degrees.  Brass borders define winter and summer solstice declination lines, and an aluminum bar defines the east-west equinox declination.  Copper analemmas define the sun’s annual path at 7:30/8:30 PST/PDT and hourly until 5/6 PM. 

Metal balls along the analemmas are placed to mark the 1st day of each month.  Black declination lines mark the ancient Babylonian Zodiacal signs, designated by different colors.  Hours are numbered for PST and PDT.  Standard time on the hour, accurate to one minute, is read on the tile surface when the gnomon shadow is just under the analemma for that hour.  The first of each month is marked on tiles in early AM and late PM hours, guiding which side of the analemma is used for that date.
