tikz beamer pgf add tag
Dr. Manuel Kuehner
 - This is a "fun" project.
 - I want to create a `beamer` presentation with a fancy title frame.
 - The goal is to have a black title frame with "bight colorful" text on it that looks like **neon** text (**glowing**).
 - It's a bit inspired by the intro of the TV show "Stranger Things".
 - Ideally, I want to stick to beamer's `beamercolorbox` approach to build the title frame template.
 - I found some (partly older) related questions but I was hoping that by now there is a simple solution available. There seems to be solutions available to generate this effect for boxes but not for text.
 - Question: Any idea how to generate a "neon glow" for normal text on the title frame with `tikz` and friends?
