>>2633351>>2633397>>2633427Thanks guys! It's an art piece at Madison Square Park called Fata Morgana, named after a particular mirage.
>A Fata Morgana is an unusual and complex form of superior mirage that is seen in a narrow band right above the horizon. It is the Italian name for the Arthurian sorceress Morgan le Fay, from a belief that these mirages, often seen in the Strait of Messina, were fairy castles in the air or false land created by her witchcraft to lure sailors to their death. Although the term Fata Morgana is sometimes applied to other, more common kinds of mirages, the true Fata Morgana is not the same as an ordinary superior mirage, nor is it the same as an inferior mirage.>Fata Morgana mirages distort the object or objects which they are based on significantly, often such that the object is completely unrecognizable. A Fata Morgana can be seen on land or at sea, in polar regions or in deserts. This kind of mirage can involve almost any kind of distant object, including boats, islands, and the coastline.>A Fata Morgana is often rapidly changing. The mirage comprises several inverted (upside down) and erect (right side up) images that are stacked on top of one another. Fata Morgana mirages also show alternating compressed and stretched zones.
