Hi YB,
I put a small scene together with a few of the blob macros.  Attached is an
image using them to create a more cone-like shape. It's not tales from
topographic oceans but it's a start. :) I like the endless curve forms that can
be created. I clipped/intersected a few inside a sphere to get a smooth top cap.

What is the protocol for posting code. Can I dump it to a message window or is
there a place on the forum to post .pov files?
Thanks.

Hi YB,
I posted the scene file for that image. Sorry, there's tons of #declared stuff
that's not used in the scene. It needs to be stripped down. Let me know if you
have any questions.

The usual places - text files for ASCII scene file, binaries for zips and such.
 Short scenes or code snippets inline with the message.

Chris was very accomodating, and changed the forum structure so that we could
now attach anything in any of the groups, so there's no longer a need to post a
render in binary images, the corresponding scene over in text scene files,
etc....

Hi Mike.

YES ! This is exactly what I want (and even more - mushrooms are 
excellent  !).
I got your scene and rendered it, now exploring in more detail..
As to the unused definition, this is not a problem, but vice versa - the
source for additional experiments - "sapienti sat" :).

Here is my collection of Dean's artworks - the source of inspiration:

Thanks a lot,

Yes. Iirc, I came across his work end seventies or start eighties? Not 
sure. I have "Album Cover Album" he co-edited at the time, and another 
one (I forgot its name presently).
