I think that this case is designed well because of its organization and creative color scheme. The triangles are all the same size and are repeated in an organized fashion. The triangles are aligned perfectly and you can sort of see how they form columns and rows. All the triangles are made of different and mostly contrasting colors and patterns, which works well in this instance. This case is just like a quilt made of scrap pieces of cloth, which I think is a very unique design to use.
