Designing a toy/game within the city. "Schlager" is a structure designed to be inserted in railing systems. I chose to work with railings because it is a common well- functioning feature within the city, so why not add an element of amusement to it?  It is a system created by steel rods of different lengths in order to create different sounds when hit.  Schlager can act as an element of surprise within your everyday routine; when walking by your keys brush against it and create 'music'.  Making you turn around and enjoy the city surrounding you.  It can be used intentionally or unintentionally by the smallest strike of your jumpers' zipper, by people of all ages.
