Well, all of this are just ways to make minecraft more, beautiful?
Ground
=======
Grass on sand: Maybe whenever you place a sand block, there is a 75% chance it is "barren" and 25% chance that it would be able to grow small patches of grass(does not need to be very big) on the sand, to add some life to it. If your block is barren, it would not grow grass, if your block is, erm fertile(?) it would have the grass generated normally or if you have grass near it.
Water
=======
Seaweed: Since that there is already grass on grass(sounds wrong?), why shouldn't there be seaweed on the ocean floor? It would add a little life underwater, besides squid. There won't be any problems about using it as air pockets or such as your head would be above the seaweed and not in it.
Sunrise/Sunset water color: The new lighting to be in 1.8 is supposed to be according to the time(am i correct?). So why can't it be that if the sunset/sunrise light is in the water, it makes the water sort of oranage, to reflect the light of the sun. Imagine you walking down the beach and you see the water have some oranage light reflecting on it, wouldn't it be sort of nice?
Sky
=======
Birds: This does not nssercerily have to be new AI, but rather some black shapes in groups that you can see in the sky now and then, like clouds except not as often. It would make it nicer to see the sky. Okay, I can't explain what I mean, but just imagine that you are seeing some birds flying.
This is currently all I have but would it help for you to respond or give some ideas?
In addition to the birds, there should be ambience, like birds tweeting and chirping in the day, and at night, crickets. Because it gets sort of creepy.
