Cloud



Clouds are an aspect of a map that appear close to the top of the map, they have no practical service and are merely aesthetically pleasing. They do however, always float towards the West, (though if players are assuming the Sun rises in the East, they float North), making it fairly simple to get your bearings. Clouds appear at layers 108-112 and will pass through blocks.

For many players, clouds have been an annoyance since they could pass through buildings. However, since the Adventure Update (1.8) this is no longer an issue as clouds pass above the maximum height at which you can build.

Appearance
Clouds will appear differently on different graphics settings, and have a set pattern.

Fancy Graphics
On fancy graphics, clouds appear as about four block tall transparent prisms. In the nighttime they turn a shade of blue and become more transparent. Their smallest horizontal dimensions are 12 x 12 blocks wide.



Fast Graphics
On fast graphics, clouds appear as opaque planes. They have no daytime/nighttime rotation. Their smallest horizontal dimensions are 8 x 8 blocks wide.

Pattern
Unlike many things in Minecraft, clouds are not procedurally generated. With a texture pack, clouds' color can be changed to anything, meaning you could have pink clouds if you so desired. The file can be resized to any size, meaning it would be possible to have a different cloud pattern each day.

Future Plans
Notch said on reddit that he liked the idea of transforming clouds into blocks and making them collide with buldings terrain etc. It is unknown if it will be implemented in future game updates.
