First time posting- Help creating this 3d point fx in Niagra

I was watching pretty lights concert online and saw this effect. I have seen something similar with holograms in films and such. I’m not looking for a hologram exactly, that’s just the best reference I can think of.

-i’m hoping to have evenly spaced particles (on a grid you could say) be (projected) on our character in game when they dance. I’m also hoping to have some type of world position coloring for the particles.

I know some things about Niagra, I am NO expert but I really want to learn how to create this with out buying a material from the marketplace. Otherwise I’m not learning anything and I really want to learn. Greatly appreciate any help on this.
