Better loading screen for minecraft

As till now we have the old 3d screenshots of a random minecraft worlds for the loading screen while loading a world which look quite boring and make it look interesting minecraft should add a live wallpaper meaning the world which we see now as not moving or we can say screenshot should be an actual world meaning everything in the loading screen should actually be a working opened world meaning now the player will now see sheeps and villagers moving while tips and loading bar in the middle of the screen.
