The camera's magic glowed, nearly instantaneously showering the globe. Electronics began to bulk up or vanish entirely while houses with more modern designs changed aesthetic completely. Clocks around the globe began to spin counter-clockwise as the camera altered reality. In just a few moments, technology, society, culture, and everything else were set back to that of the year 1985.
However, instead of actually traveling through time, the camera simply altered the world so that it was just at that current level. As such, everyone who was alive for the 80s didn't suddenly regress, but rather everybody changed to be 80s versions of themselves... mostly. As the camera's magic thrives on chaos, it also altered about 10% of the global population. Some were different ages, other genders, and a few unlucky souls became animals or objects so that the population's number was closer to the original 80s.
The Mall changed from a modest, modern looking mall to a totally "trendy" 80s mall with bright colors and over-the-top displays. People walking around gained big hair and very weird new clothing styles. Being at the center of the change, Rhianna, Emma and the boys they had been taking a picture of were practically guaranteed to be in that 10% that were additionally altered beyond being 80s equivalents.
The question is, how extreme were their changes? What are their changes? What will happen next?
