+Inspiration
+===========
+
+This design was inspired by :user:`cajhne`'s `original proposal`_ and the
+ancient symbol of the ouroboros_.
+It features a snake moving in a circular trajectory not only as a reference to
+the Python programming language but also to the `wheel package format`_ as one
+of the distribution formats supported by setuptools.
+The shape of the snake also resembles a cog, which together with the hammer is
+a nod to the two words that compose the name of the project.
