This allows you to check out interactive code at http://mpacer.github.io/thebe-test/.
You need to have jupyter installed(pip install -U jupyter) and run a notebook server from a place that does not modify the origin call from your browser (e.g., virtualenvs can mess this up):
jupyter notebook --NotebookApp.allow_origin=* --no-browser
In the simplest of cases, this should work for you.
