The "Cool S", also known as Superman S, Stüssy S, Super S, Pointy S and Graffiti S, as well as many other names, is a graffiti signature of popular culture that is typically doodled on children's notebooks or graffitied on walls.
The Cool S consists of 14 line segments, forming a stylized, pointed S-shape. The tails of the S appear to link underneath so that it loops around on itself in the same way as the infinity symbol does. The Cool S has no reflection symmetry, but has 2-fold rotational symmetry and tessellates with squares. As illustrated, a common way to draw the shape begins with two sets of three parallel, vertical lines, one above the other.
The origin of the Cool S is unclear. The name 'Superman S' comes from a belief that it was a symbol for Superman, whose costume features a stylised S in a diamond shape, but that shape is quite different. Similarly, the name 'Stussy S' is from a theory that it might be a symbol of the American surfwear company Stüssy. However the company says that is not the case. Because its drawing is aided by lined paper, it is likely that it originated in a middle school setting.
