We've been disappointed by how unambitious people are in this sense with Jupyter notebooks. They haven't pushed the medium all that hard; there is no Citizen Kane of Jupyter notebooks. Indeed, we're barely beyond the Lumière brothers. Examples like Norvig's notebook are fine work, but seem disappointing when evaluated as leading examples of the medium.
Aspiring to canonicity, one fun project would be to take the most recent IPCC climate assessment report (perhaps starting with a small part), and develop a version which is executable. Instead of a report full of assertions and references, you'd have a live climate model – actually, many interrelated models – for people to explore. If it was good enough, people would teach classes from it; if it was really superb, not only would they teach classes from it, it could perhaps become the creative working environment for many climate scientists.
