This action consisted of three different child faces of ethnic backgrounds: Asian, Black and Indian. The mouth had an opening just where the coin to release the supermarket cart is inserted. Each coin would symbolically feed a child. Under the image, it says: "You can feed a child for two days with what you spend renting this cart. HELP"

I think it's brilliant. Imagine going around the store with this cart. Shopping for groceries, for instance. I couldn't think of anything else for the entire shopping trip, and far beyond that. It should be very effective in that sense. {As a side note, this wouldn't fly in 'political correct' USA, of course... They'd probably just get sued for racism, entirely missing the point.}
