Every known detonation of a nuclear weapon, be it in anger or in testing (only two have ever been used in anger). Data stops in 1998, so North Korea's potential, unconfirmed detonations are not shown; neither are further Pakistani or Indian. The southern Indian Ocean potential detonation by South Africa was never confirmed, and is also absent.
I first saw this video in a slightly different form on YouTube, and watched because I thought it would be "cool," but instead walked away with a sick feeling in my stomach. People need to see this. 2,053 nuclear detonations.
The original attribution text is as follows, because this guy deserves credit:
"Japanese artist Isao Hashimoto has created a beautiful, undeniably scary time-lapse map of the 2053 nuclear explosions which have taken place between 1945 and 1998, beginning with the Manhattan Project's "Trinity" test near Los Alamos and concluding with Pakistan's nuclear tests in May of 1998. This leaves out North Korea's two alleged nuclear tests in this past decade. Each nation gets a blip and a flashing dot on the map whenever they detonate a nuclear weapon, with a running tally kept on the top and bottom bars of the screen. "
I set it to some music that is more appropriate to the situation. The people at YouTube blocked it in 227 countries, including France, the UK, Russia and the United States. If there are any countries that DO need to see this, it's them! This coming from an American citizen (born here and everything).
Please, pass it on. I'm not a tree-hugging hippie, but if this doesn't make you say, "Wow..." you need to have your head examined.
