I decided to abandon bullet-based decks a few years ago for images and narratives (even when dealing with programming), followed by a live-coding demonstration; anecdotally, the response to talks I've given in this format has been great.

Years later, people will spontaneously write and reminisce about such and such a talk on e.g. extending Roxygen.

This is, incidentally, the same format as my daughter's bed-time stories; coincidence?
