The success of communication is measured by the listener. If your message is not understood, you have not been successful. The video below is an example where a Planner has likely had these words in mind, as he developed a slideshow to support a discussion about "density".
What is noteworthy in this video is that effort has clearly been taken to gather and show images that help describe density to the audience in a way that is informative, and will likely also change perceptions about density.
Showing examples of built projects to illustrate points is not a new idea; is not complicated; and, is not technically difficult. Unfortunately it is still far too uncommon, and projects are discussed in a contextual vacuum and with abstractions. Why? What is your excuse?
