I got bored.
First one's just showing the dominate 3D outlines and one dominate line that runs straight through the middle.
Second one is outlines and such, with that you can CLEARLY see that what some thing is his "head" is part of the architechture behind. You can even see the 3d shape of a rectangle that is -clearly- not the shape of a head unless they decided to go back to polygons for some reason. And the last is the original for comparision.
The end.
