The design firm said it will donate $1.51 to the charity for every visitor to Jump In. "Right To Play uses the power of sport and play to transform the lives of over one million children every week across Latin America, Africa and Asia. They work in some of the most disadvantaged communities to provide an education, teach vital health skills and promote peaceful communities," the charity said on its website.
