On Saturday night, one of the most famous buildings in the world was used to send a powerful message about animal welfare.
The Empire State building was home to the one-day show 'Projecting Change', launched to promote new documentary 'Racing Extinction'which airs on Discovery Channel in December.
Images of birds, bears and tigers were projected on to the south side of the Empire State building, including Cecil the lion, who was killed last week in Zimbabwe.
Here are some of the best pics from the show...
