I simply must give my observation of this fine piece of art.
Well, when i see the lines, to me they represent the hard times in life we must endure, the eye being the absolute true happiness every human being craves. Seeing as the lines aren't straight, it easily represents what it takes to achieve said happiness, hard work, sweat, tears, even pain for that matter. You must go through these obstacles, to finally achieve what you've been dreaming of, and when you do get there, it's a feeling nobody can describe, you have to feel it for yourself, that is the beauty that the eye holds deep within those lines.
Anyways, i hope that makes sense 
Mmm, that's an interesting take on this fine piece. Truly each tiny segment of this piece of art encompasses many things to many people.
Take lower frontal foreground leg, for example. I, for one, see it as symbolic of destiny. The way that it at first appears quite defined and then fades into the abyss is clearly a parallel to how, while we may believe we can predict the outcome of our actions, the real future is far off into the distance, faded so greatly that no one can see it until it arrives. This is the leg that carries us to our futures, our destinies.
