During the research phase of a recent identity project, we spent some time revisiting numerous examples of what we like to call “fluid identities” — logo systems that use multiple iterations of a mark (or series of marks) to communicate a particular aspect of a brand. These might take the form of a logo that changes with each viewing, or a singular mark that gets impregnated with different imagery, depending on the context. At one point, these types of projects were few and far between, but now these isolated examples have grown into a full-blown trend. The days of the static logo are certainly not extinct, but this persistent way of thinking about malleable identities seems like a portend of things to come.
