For a moment, it looked like the Coinherence Symbol, but that's based on a circle.
This is an octagon, split in quarters in the middle of line segments rather than the vertices, then connecting all the vertices in somewhat of a web-like manner. The end result, if you took away the quarter split, is a really cool-looking eight-pointed star surrounded by its originating octagon.
Overall, it's a relatively basic geometric design that looks really awesome. Do you plan on coloring it?
