I didn't originally intend this as a tattoo, but this seems the most appropriate place to put it. This is a design from a sketchbook I kept years ago, reworked on my computer.
Most of my designs are drawn with any particular intent in mind to start off with, so it doesn't have any kind of symbolism. The title however, comes from the idea that it is a circle with movement inside of it. Some people have told me that it also reminds them of a mother's womb somehow.
