You've never seen the Venn Diagram like this before: a flowery diagram for 11 sets of objects, made by Khalegh Mamakani and Frank Ruskey at the University of Victoria in British Columbia, Canada:
One of the sets is outlined in white, and the colours correspond to the number of overlapping sets. The team called their creation Newroz, Kurdish for "the new day". The name also sounds like "new rose" in English, reflecting the diagram's flowery appearance.
To find the rose-like diagram, the pair had to comb through myriad potential diagrams, represented as lists of numbers corresponding to the way the curves cross. Sifting through all of the possibilities for an 11-set diagram would be an impossible task even for the combined might of Earth's computers, so the researchers narrowed the options by restricting the search to diagrams with a property called crosscut symmetry, meaning that a segment of each set crosses all the other sets exactly once.

Quoting one web site, after the tests started at the Nevada Test Site: "Almost overnight, Las Vegas ushered in the age of atomic tourism. Fueled by a series of press releases from the Chamber of Commerce, visitors from around the country descended on the city in droves to witness the mushroom clouds first hand. On April 22, 1952, 200 members of the media were invited to broadcast from Yucca Lake, just ten miles from the epicenter of a major blast. As the bomb exploded on televisions from coast to coast, the country was caught up in atomic fever."
Quoting another site: In the summer of 1957, an article in the New York Times explained how to plan one's summer vacation around the "non-ancient but none the less honorable pastime of atom-bomb watching." Reporter Gladwin Hill wrote that "for the first time, the Atomic Energy Commission's Nevada test program will extend through the summer tourist season, into November. It will be the most extensive test series ever held, with upward of fifteen detonations. And for the first time, the A.E.C. has released a partial schedule, so that tourists interested in seeing a nuclear explosion can adjust itineraries accordingly."
Sure, it was shared on slides and postcards instead of Twitter, and broadcast on network TV instead of sent through Facebook, but it's hard to imagine how there would be "new levels of desensitization." People expected nuclear powered cars and airplanes and rockets, and new ports created by detonating nuclear bombs. Quoting Wikipedia: "Nuclear power was seen to be the epitome of progress and modernity."
The fake pictures, as whitcwa succinctly says, pale in comparison to what actually happened.
