The next morning a package arrived at Tomas's apartment, he opened the box and discovered a device that was apparently called a "Chronivac 4.0" He turned it on and started looking through the different options. When he discovered the World Change option a thought occurred to him. Wouldn't it be neat if everyone liked to be show off their naked bodies just like he did.
So he input "nudity is normal", pressed enter and then tried not to fall out of his chair as a wave swept over the entire planet from the device.
When everything had settled down Tomas looked around and discovered that he now owned less clothing than he did before and what he did have was more revealing than before. He turned on the TV to watch the news and to his shock, nearly everyone was naked! And what's more, no one seemed to notice or care. He looked out his window at the city below and saw the full extent of the changes.
There seemed to be a fairly even split between naked people and clothed people, though "clothed" was a bit of a stretch considering how little they were covered up. There was a billboard on top of the building across the street that now had the huge breasts of the female model bared for all to see.
Tomas looked back at the Chronivac and realized that what he has typed had become real. He couldn't help but wonder, what other sorts of changes could this thing make...
