Clos is a fictional clothespin brand, developed as final Bachelor Degree project. The aim of the project was to create an unrealistic brand for an unrealistic purpouse. We were assigned the task of giving life to an anonymous everyday object, creating a brand from scratch for it and expressing its values through various touchpoints. To communicate the brand Clos to the public through an interactive experience, we used music as the medium to convey the value of harmony. Therefore, the clothespins become the keys of a piano for a musical arcade game: by using a keyboard of clothespins as a controller the players are able to play while catching clothes for the laundry. A real size working prototype was created using Arduino and Processing.
