Hi,
For all, I made a small package with the textures I used in the video- there
are more to come and more shaping of the clouds.
You can take a look here:

Hi at all,
The tools are there for anyone to take a look at and help

I'm not very good with GIMP, so I'm hoping that
someone else
can spend some time improving them.

Hello,
Imposters would be good, if they worked :(
I think our current clouds if they had slightly better textures and
smoother alpha blending would look pretty good.

One thing that Mark Harris' clouds considered was lighting I believe.
Portions of the cloud that were shaded were darker and portions of the cloud
most exposed to the sun light were lighter. I don't know the exact
algorithm, but I believe he was doing some extra work with lighting. Then

If any other cloud layer above, then from ground look same as without patch

I placed ufo in the middle of clouds and made a spin by pressing left cursor.
Then all the clouds were turning toward me, changing their order.

Is this applicable to the trees, too?
The cloud code does a single bubble sort pass per frame, to avoid the
performance penalty of sorting the entire cloud set each frame.
