Some form of this question is the one I'm most frequently asked. I have many answers but the one that's most honest is probably the least satisfying: I do it because I like it. I like bringing arms to life from unassuming piles of desk clutter. I like thinking about all the surrounding ideas, reading the research, and discussing it with everyone I can. It seems like the right thing to be doing.
More often, my answers to this question are: 1. as a gesture of friendship, 2. to learn more about oil painting, 3. to uncover an objective standard of taste. These are the answers I'll be addressing in this blog using examples from art history, philosophy, color theory, and computer science.
