Kind of funny observation, but the lights at the bottom of the website actually technically use more IRL power to run...
I have a CPU monitor on my Stream Deck and when I scroll down the page to the lights, my CPU usage* immediately jumps from 1/2% to ~30% (Ryzen 7 7700x) and my CPU fans ramp up as if I'm gaming. Scroll back up and it goes back down. They're just hilariously unoptimised.
(* for those wondering, I have GPU acceleration turned off on Chrome so YT videos play better, less stutter)
