Here's my own attempt at a Fibonacci antoblob floor... I got tired of
waiting and made my own source ;-) I don't fully understand how to do it but
I'd like to have larger gaps between the tiles.

It's not TODAY longer, but I posted it to p.t.s-f anyway :)

I like this floor !
=)
Please post another image if you improve it.

Sorry. I got so excited about Chris' and Xplo's suggestions.

If you look at the source code I just posted,
you will find a comment I made in the code
that shows how to move them a little bit apart.

I've done this by saving the image imn ppm format.
Then search/replace space with comma (POV needs commas between values)
and stripping the header except the dimensions (it's handy to leave
these in).
Now you can read it with POV.
PoD.

I like that one Tor. I'm jealous.
Now, if you scale the blobs larger as they move outwards, and increase
distance from center after each blob, pow(radius,??), then this would
be what I would have liked to achieve. I can do this with spheres but
your antiblobs would give a more realistic result and avoids the
spheres intersecting :)
I must find time to play with your AntiBlob macro.

Thank you. - And I'm glad you are jealous =)

Maybe I need to have a look at your code once
more, because I'm not sure if I understand correctly
what you describe above.

Have fun !
(The math in this macro may need some adjusting,
and I'll look into that a day when I'm in math-mode. :)

Can you please tell me where can I find appropriate
information about the ppm format ?
(I.e. Info about structure of the header- and colour-
information.)
And is there any "free" programs that can convert to
this format ?

Free as in price or philosophy?
Free or low in price:
POV-Ray. :-)
GraphicConverter(not free, though nicely priced shareware, Mac only).
I don't know of any others, though that is mostly because I have never
used the format. Programs that use QuickTime can *read* it with no
problem...

netpbm, the programs that introduced the format in the first place.

In my p.t.s-f post replace constant size spheres:
sphere{ z*Rad, 0.1 rotate y*Count*Inc }
with spheres of increasing size:
sphere{ z*pow(Rad,1.4), Rad/16+0.055 rotate y*Count*Inc }
( You can delete the blob and bounding sections)
