I decided I needed to learn a 3D rending software. I found Blender which is Open-Souce, and, hence, free. I read a bunch about the user interface and found it quite daunting because it was unlike any software I had used. Well, it was like all the software I had ever used, just mashed-up in a way I hadn't encountered yet. In 2 hours I had made it through most of the tutorial to make a gingerbread man and had a better understanding of how it worked. I was rather elated at the progress I had made. I recalled what it was like to learn something new and get good results—the kind of thing that fired my obsession with computers in my teen years.
