Nice scene.  That helped out a lot with the sand part.  I never thought of
using a very small bozo pattern.   I think Steve Gowers' pattern is scaled
too small however as the sand has some artificial looking strips in the
lower right corner (especially evident once you take out the 'crackle').  At
the bottom of the message is my (corrected?) version and I have used 'waves'
instead of crackle to give an interesting twist.

The problem with textures as I'm finding out is they don't actually change
the surface of the object so when you try to interact with other objects you
get unexpected results.  You'll notice that Steve avoided any problems with
the bucket and the sand by not showing the bottom of the bucket.  And who
would notice anyway with such great looking shells!

Now the real problem is getting transparent water on a large scale and
getting it to interact with the sand in a realistic way.

Thanks for your help, the sand texture looks great.
