TRIVIUM 3: The first television image used for a test pattern was the dollar sign. That 1928 image was chosen & displayed by inventor Philo T. Farnsworth (1906- 1971)
TRIVIUM 4: "E Pluribus Unum" is used on many of our country's seals and most of our currency and coins. During the American Revolution, the Continental Congress issued a three-dollar bill bearing the motto, "Exitus in Dubio Est," which translates to “ The Outcome Is in Doubt." Despite congressional pessimism about the war, John Adams, Ben Franklin, and Thomas Jefferson proposed the more prophetic motto, "E Pluribus Unum" -- "One From Many." The motto first appeared on the Great Seal of the United States in 1782. The Great Seal, however, didn't appear on U.S. currency until 1902.
TRIVIUM 5: What's with that creepy single eye?
The so-called "all-seeing eye" that sits atop the pyramid on dollar bills was included as a reflection of divine providence. This was not the only option that was considered to fulfill that desired theme. A depiction of the Children of Israel in the Wilderness was also discussed as a possibility.
