I've used this avatar since June 2012. I started to use it on SEOClerks. I can't tell you much about it though, because there aren't much too it. I just found a cool-looking image and I cropped out the eye from it.
However, my eye is a bit different from other similar ones, and even different from avatars that are identical to this one. Because my eye has an X in it. That X, stands for Level X, which is the highest user level one can reach on SEOClerks.
