In the past, I put together a stick figure version of the Vitruvian Man – only in my case it was done as a dragonfly.
It's based on the Happy-face Dragonfly, also known as the Paddle-tailed Darner, and is taken from a photo, ensuring that the proportions are correct.
I recently commissioned a wonderful artist, Sabine Deviche, to do a professional version of the Vitruvian Dragonfly. Here's the result, which is just beautiful:
I love the details in the wings, and everything else about the drawing as well. It has a very classic feel to it.
