Atmosphere Fade

I feel that it would be cool if once you get above a certain y level (probably a little ways above an average mountain peak), the higher up you go, the darker the sky gets until you are in space. In space, the sky is dark but filled with stars. If it is daytime, you can see the sun in space also. This would be a visual change. I think this would add a great aesthetic to Minecraft for anyone who likes to build futuristic stuff like space ships.
