Actually its Celtic based nothing really creative at that .. celtic knot .. as you may notice this is flawed .. it has two a cross and a clover inter-winding but its two separate lines, two shapes .. while the good knots are usually made of one (that's the skill) .. the lines at the center (with the pencil) will modify it that way hehe
I think it's the circles in each "loop" that look like eyes to me, giving it an illuminati effect. It's very cool, regardless.
