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?

Maybe this goes in the right direction.
