Fata Morgana by Teresita Fernández.
Madison Square Park has been transformed with the largest and most ambitious outdoor sculpture in the park to date. Fata Morgana, by New York-based artist Teresita Fernández, consists of 500 running feet of golden, mirror-polished discs that create canopies above the pathways (which, by the way, all lead to the newly renovated and re-opened Shake Shack). A "fata morgana" is a mirage seen above the horizon line, and this sculpture "perforated with intricate patterns reminiscent of foliage, will create abstract flickering effects as sunlight filters through the canopy, casting a golden glow across the expanse of the work, paths, and passersby." It really is quite lovely, and in the park until this winter.
