I love doing The Big Picture series for Engadget, even though it can take a lot of hunting to find a striking photo with a tech angle. I believe in the idea that, by creating some emotion, dramatic images help us grasp heavy concepts in a way that words alone can't.
Another is that I learn a lot of interesting stuff while researching them. That includes things about art, astronomy, science and even weaving. That information seems to stick in my head as it's indelibly associated with a powerful image.
Many of this year's Big Picture images make interesting statements about the impact of technology on humanity. And although some of the images were created by accident or without artistic intention, they're often full of symbolism and irony like any other works of art. I think a great example of that is the first item on my list.
