It was another music video from Koit, it seemed. Then I noticed the description. Really, multiple possible outcomes of how the animation will play, let alone 531,441? I was a bit doubtful, so I kept in mind what eggs I first saw and restarted the animation. Sure enough, the same eggs had different decorations by then! Now that's something you just can't replicate on YouTube. I'm giving a full five star rating for you pioneering this concept.
