I can't see your avatar on Chrome 47.0.some_numbers
I was hoping this would be about how you chose your avatar. In that case, I've had two since being on this forum: Boccioni's "Dynamism of a cyclist" and the barred owl.
I chose "Dynamism of a cyclist" after seeing it at the Guggenheim here in New York. However, it's abstract and hard to see in a small image. The barred owl attacked me on a run years ago. It's sort of a power animal for me, if such a thing exists. A friend called it epic, so it's staying for now.
