“It ought to be solemnized with Pomp and Parade, with Shews, Games, Sports, Guns, Bells, Bonfires and Illuminations from one End of this Continent to the other from this Time forward forever more.”
— John Adams to Abigail Adams, Philadelphia July 3rd. 1776
While watching the fireworks display at a nearby park last evening, we witnessed a lot of great effects, including a happy face. Check it out in the video.
I got curious about what effects there were out there and so I looked in WikiPedia for some answers. I was amazed at the many types of effects applied to modern fireworks displays. Among the many effects there is the ring effect; the happy face is a derivative of the ring.
I also found the quotation from John Adams at the top of the WikiPedia article.
