If you need the animated version i really can't provide it since it's made with wallpaper engine so your only options are to not use an animated version of it or use wallpaper engine on the phone (Android only).

I also happen to have the edited version of it as a still image though https://drive.google.com/file/d/1E8bSaJwPgqwswueQWH3_oy0O1Pmcu8So/view?usp=drivesdk

The original source is in the description of this workshop item (https://twitter.com/oekaki_nekosan/status/1455855298921463810?s=20)

Do you have the picture at 16:9?I want to use it as a lock screen
