Letters are very strange creatures. They’re the building blocks of our entire system of written communication, but when you get right down to it, they’re really just pictures. They deliver a direct message to the reader, but they’re also visual elements that can vary in color, shape and personality. This makes them especially popular when it comes to the look of a company’s logo; just a couple letters can convey a world of meaning. But it also makes them very tricky to work with.
