Answer 1

It's just an image you may select as your avatar.

It's called the Vitruvian Man. It's a famous sketch by Leonardo da Vinci.

Da Vinci drew it as an example of what he believed were perfect proportions. The man is aligned perfectly with both the square and the circle when his arms and legs are in different directions. If you examine it closely you'll see geometric shapes and straight lines.

"He believed the workings of the human body to be an analogy for the workings of the universe."
