Thank you so much for reading! I don’t think this post would have happened without your kind words and curiosity 
No secrets I’m afraid but I can share more: the idea for the YouTube video URL input box came from my exploration into making a functional audio visualizer. The waves are always the same for now (so, they don’t detect/depict the audio i.e. not a functional audio visualizer) HOWEVER I still found that the waves pair really well regardless of whichever audio you decide to play.
^Sorta like this dancing GIF which pairs well with any music… 
In the future, I want to explore an “audio to wave” version of https://community-voices.vercel.app where community members can speak and leave “triangles” of their voices 
An on-brand alternative to thumbprints!
