Dynamic Title Screen

I'm sorry if this has been suggested before, I'm not good with searching things, but this is something I've just came up with.

The current title screen background is just a bunch of flat textures placed in a cube shape, and blurred in order to make it look 3D. I think it's time for an actual 3D model to be used on the title screen.

However, that's not the main point of this suggestion. The main point would be that the title screen background would be the spawn chunk from one of the player's worlds! The world would be randomly picked every time you boot up the game, and if you didn't have any worlds created (e.g you've just downloaded Minecraft on a new computer, or you are new to the game), it would be just a default non-playable template world embedded in the game itself.

I understand this may cause performance issues however, so there would be an option to turn it off, and if Minecraft detects the computer may not be able to handle it, it would be disabled automatically. When you turn the dynamic title screen off, it would just be the title screen as it is right now (the blurred textures in a cube).

I also understand this may cause a longer loading time, so that's also why I said you could turn this off. Additionally, if the game fails to load a world for whatever reason, it will try to load another world, and if it fails again, it will default to the classic title screen and show an error message saying "Your worlds may possibly be corrupted! If you are unable to play any of your worlds, please try to restore from a backup."

Anyway, any thoughts? What do you think of this?
