These cute little Tic Tacs of color are popping up all over the design world. Like many abstract symbols, the hot dogs can be used to mean many different things. Sometimes they denote movement or sound, such as in the Logo for Snap. These lines, reminiscent of those drawn out of shocked cartoon people by children everywhere, can denote an idea, a feeling or a literal meaning. But no matter how they're used in design, they are a powerful symbol of an upbeat emotion.
