It isn't often that a sundial face is created before the gnomon is attached.  In Shelbyville IN a large, circular art piece in the form of a sundial, was created at the Blue River Trailhead early in 2024.  If they had chosen an analemmatic sundial, a walker of the trail could have simply stood on the appropriate date and used his or her own shadow to tell the local solar time.  But Shelbyville residents have a more ambitious plan.  The artistically paintedd design is a typical horizontal sundial, requiring a real slanted gnomon. In a news article by Jeff Brown in The Shelby County Post for Nov 12, 2024, "The Blue River Community Foundation received approval Tuesday morning from the Board of Works and Public Safety to purchase and install a gnomon that will turn the art piece at the Blue River Trailhead just north of downtown Shelbyville into a functioning sundial." According to the article, the completion of the sundial will be paid for by grants and private donations.
