This isn't an abstract shape.

 

It’s periods of the same size, the same weight, on the same baseline but from different typefaces. All periods aren’t the same. Most of them aren’t even perfect circles. A few of them are squares. But all periods are different because they were all made by different people. They started as an idea for a specific typeface. That was then made by hand. By an artist. An artist that can take something as simple as a dot and turn it into art. And if they can do that with a dot, what do you think they can do with the rest of the alphabet?
