rude. first of all, saying the project is just projecting the shadow and the shadow isn't a shadow of the trash, is simply false, and denies credit to the artists. You also aren't going to see the physical structure of people in the trash, because it's set at varying degree's from front to back in order to create the shadow. If you'll look a little closer, the stick holding what looks like a cigarette is in the back, but whatever piece of trash they used to make the hand is closer to the front.

It's not bad picture quality, you just have no critical viewing skills and don't know how to appreciate a true work of art when you see it, nor understand the tremendous amount of effort involved in the task of creating something like this.
