We have just created a recursive side so the recursion is strong in us. The corner in her turn is recursive as well. Lets focus our eye on some of the details.

In the bottom right corner a utile can be recognized. The top right is our friend side. The bottom left is also a side, but now turned and the recursion starts in the top left, where we find our own corner but of a lesser order.

Go on young artist, Eschers Square limit is awaiting us.
