Why 3D Brain? Well, I guess my brain is the only part of me responsible for all of this stuff. This website has a little bit of right brain, (art) and little bit of left brain (programming). I'm not saying that my brain is "THE only 3D Brain" and my apologies to those who have better 3D brains than me.
