Intro
Definition: a video that has been digitized so that it can be
controlled from a PC and displayed directly on a computer monitor.www.digitalsignagetoday.com/glossary.php

contemporary culture expressed in video
Scenarios
I need a video that demonstrates the physics of a human shoulder
I need thirty seconds of footage that shows an artist painting
I’d like my students to know what it was like to live through the Watts riots in the 1960’s
