Hat tip to Daniel Pink on this exhibit by R. Luke Dubois at the Smithsonian Museum.
"In a series of prints called “Hindsight is always 20/20,” he’s taken the words of each speech, noted their frequency, and rendered them as a Snellen eye exam chart – with a President’s most-used words in large type near the top and his less-used words in progressively smaller type toward the bottom.
It’s a mashup – one part word cloud, another part optometry. And it works. You get a good sense of how much the times dictate the words. It also offers a sly commentary on each President’s – wait for it – vision."
