Fireworks... They are simple and yet profound. Gunpowder, metals that burn different colors, and physics transformed into a shower of lights and sound. The deep boom of a firework and the shower of sparks they generate can resonate with people and create curiosity... perhaps introspection... or just merely amusement with the lights, booms, and music.
In the latest displays a county had contacted a special firework specialist who had claimed their fireworks wouldn't start any random fires, and after some investigation it turned out the fireworks had no chance of setting a random fire that would get out of hand. Really it was almost like magic... The firework specialist enjoyed his craft though, and with a pinch of magic believed he would deliver a reality that everyone would enjoy the most. His displays tended to be spread out with all sorts of different colors and patterns intended to resonate with people. Giving a sort of "Illusion" showing a what if? of sorts. It was stronger when the lights were bright and the sound resonant, but if the "Illusion" truly resonated with someone it would linger. None of the displays were any more or less magnificent than the last, but they were all different. All but the final one that was the "Grand Finale" A culmination of the last displays all put into a single one. A person would resonate with everything that they did prior and welcome in a new reality where they'd feel the most enjoyment. Least that was the theory. It may take a couple of viewings to fine tune the reality for everyone to be truly as happy as they could.
