Chris Jordan's artwork which is built around highlighting and demonstrating the excesses of the American culture are a fascinating take on some vast numbers. This is a great idea, representing some shocking data in a form that breaks away from tables of figures, to deliver a message that we can relate to more easily - perhaps.
Chris Jordan's Site has many images of the works, with zoomed in versions that reveal the enormity of the numbers in question. Below is one example showing the image in full, then some closer views. This piece is called Plastic Bottles, which "depicts two million plastic beverage bottles, the number used in the US every five minutes".
