Yesterday, Banksy unleashed his enchanting mobile waterfall truck upon the streets of NYC as the latest piece in his month-long open air street art tour of the city. He's now updated his site with the video below, writing, "I’m not posting any pictures today. Not after this shocking footage has emerged..." Warning: if you are easily upset by images of dead cartoon elephants, this video is not for you.

Reading between the lines, this seems like it could be a reference to the neighborhood DUMBO—perhaps his latest piece is already there waiting to be discovered, or maybe the waterfall truck will be there later tonight. We'll update once we learn more information about the scavenger hunt.
