Designer makes helmet to combat work stress
Japanese designer Tomomi Sayuda has made a special role-playing kit for office workers, to help relieve stress at work - an important issue in Japan.
Called Mask of Soul, it involves wearing colourful, cartoon-esque helmets to take on a new persona. The idea was borne of a family tragedy.
The idea has not found a commercial backer, but the prototype designs have been exhibited in art galleries.
