A visual instrument is an instrument that generates geometrically and aesthetically appealing temporal-spatial patterns if it is skillfully manipulated by a player. We present new types of geometric visual instruments having pinnate forms that are used by rolling one instrument along the other. We designed and fabricated the proposed visual instruments and confirmed that they can be manipulated skillfully and they provide a way to explore new types of manipulative play and performances.
