Apple

I was finishing laundry when this animation occurred for some reason, and had enough time to pull out my phone! It’s pretty neat but I do not understand its purpose lol. I think I’ve seen this once before recently but it ended before I could even process it. Do y’all have any ideas as to what it could be? I googled incase this question had already been answered but all I found was a text thread on this subreddit from a while ago with no solution. Please ignore the Gaussian blur, I was rushing to get a video of this and had to edit the background 😂 Thanks for any insight!
