Seoul, Korea studio UnPlug Design came up with this near-genius idea for providing makeshift soccer balls (okay, footballs) to third world children who otherwise wouldn’t be able to afford them. A wave-like pattern is printed (or perhaps perforated?) on the boxes in which material aid to these countries is often shipped; once the box is empty of its contents, children and aid workers can follow the patterns to break down the cardboard and assemble the ball. More background and pictures here.
