I really don't know what else to call this, and there's nothing I can think to say about it, except that I came across these two press photos, shot many years and miles apart, of men jumping up to touch a new sculpture.
The first, from 1961, shows Atlanta mayor William Hartsfield testing a mobile in the terminal of the airport that would eventually bear his name. It's for sale here from Historic Images:
The second shows an unidentified office worker in the sunken plaza of the McGraw-Hill Building, part of the Rockefeller Center expansion finished in 1972, trying to reach the tip of Athelstan Spilhaus's sculpture, Sun Triangle. It's for sale here:
The photo has no date, but Sun Triangle was installed in 1973, which matches those folks' look. Better known as a scientist than as a sculptor, Spilhaus aligned the sides of Sun Triangle to align with the sun on the equinoxes and solstices. He was also the guy behind the balloon that crashed in Roswell in 1947.
