A Munich-based design studio is proposing a unique alternative to washing clothes by hand in developing countries. Swirl is the concept design for a giant candy-striped ball that you can stuff your clothes in; roll it around using removable handlebars or by kicking it around, and that rolling motion launders the clothes inside. It has the added benefit, the studio claims, of doubling as a giant soccer ball and a water transporter. What do you guys think? Good idea? Bad idea?
