The creativity of people is amazing.   The National Debt is profiled as a Road Trip with explanations from 1900 to 2016.   I like the speedometer and the visuals of the map together with Presidential 'landmarks'.   The most powerful invention in the 20th and 21st Century is media because its power frames arguments and perceptions.   The power of movies (visual imagery) stays with us far longer than anything else IMO.
