"Bicycle Repair Man" script showing a "zope-esque" prototype in less than 200 LoC using multiple inheritance and mixins.
This prototype was presented in Python Brasil 2011 in Sao Paulo, explaining at once a bit about what Zope does (did), and showng the capabilities of multiple inheritance.
(and likely not touched since).
