This image symbolizes my philosophy/project. It captures so many concepts: dialectic, recursion, spanning layer, e pluribus unum (from diversity unity), symbiosis and speciation, asymmetry, complexity (braiding). The design is by the Welsh artist Jen Delyth. You can see different variations of the design and even order it on a T-shirt (I have it) at her web site Keltic Designs.
