Lumia is intended for both parents and children. Lumia's metal ring is placed in a common room. The ring serves as an additional element, the ring can serve as storage or exhibition. The toys can be used in all times and also without the metal ring. All loose toy parts are equipped with multiple magnets so that everything can be connected to each other in a random way. At the end of the day, the toys can be placed in the ring, again the magnets work as a connect system. When the children have placed the toys in the ring in a way they want, a shadow play is created in the room, which is created by the incidence of light on the toy construction. This way, a new toy story is created through the shadows again and again.
