Rubu is a low-cost shippable playground for children in the Syrian refugee crisis that seeks to alleviate war trauma through play. Compared to basic needs like food, shelter and water, play is often dismissed as a luxury for kids in emergency situations when, in actuality, children dealing with psychological trauma from war need play more than ever. Inspired by pop-up books, Rubu makes play accessible in any situation by utilizing inexpensive easy-to-ship cardboard material that expands into a pop-up playground.
