Am i weird for this?

Okay okay, so basically...
I'm geeking out over the subscribe button on YouTube?
Why?
Because when a YouTuber tells you to subscribe no matter the time, it shimmers.
I clicked back over and over again but, it still shimmered and it's so cool I need to know how they did that.
And yes, I know this isn't new but I didn't care before, I care now and I want to know now.
