Standardisation

In accordance with the growing trend towards standardisation, it will not be long before clouds lose their fluffy edges and become smooth. Instead of suddenly appearing out of the blue, they will make their entrance at specified times and move across the sky at a measured speed. In contrast to their present dappled and indeterminate appearance they will be limited to three plain colours, white, pink, and grey. They will no longer run into one another or break apart, but come in three distinct sizes, large, medium, and small; and three shapes, spherical, bulbous, and dodecahedral.
