I am looking to create an effect where I have a tube and there is algae
growing
off of it. The rough shape is similar to this image:
http://www.fortunecity.com/greenfield/hawks/191/ChekJawa/chek3.jpg
That seems to be a real thing so no pov model is available :).
I am wondering whether there is a tool which generates such things. It is
not
quite landscape or tree generator (needs to be semitransparent and no
branching
and does not grow on a plane but on a tube, also needs to "wiggle").

How about using 'sphere sweep' and make it by hand!?

They seem to have removed the image. It can be found by GIS for:
"colorful tube anemone" Cerianthus

It's there for me. You could try a free modelling program like Wings3D,
www.wings3d.com
You would create your model/s in Wings, and then import it/them into
free PoseRay, http://mysite.verizon.net/sfg0000/
Add your textures, and then export the models to free PoV-Ray.

This is a chore. I would need to ensure that paths are
a. Starting from the defined shape (here - cylinder)
b. Wiggle randomly
c. Do not self intersect
d. Do not intersect other wiggly shapes
The "no intersections" condition means that wiggles will be more constrained
close to the base shape (cylinder) and grow in amplitude away from it.
This is a chore to code by hand. You could also make trees by hand but it is
painful enough that people have specialized software for the purpose. I have
done a few sphere sweeps by hand and it took time. Doing a few thousand
needed
for this effect by hand would take an incredible amount of time.

I just did a rough calculation and I need about 200 of these "tentacles".
So it's not as bad as I thought but still very painful. Any automation tool
would be good to know about.

It sounds like you want something like this.

Thanks, that's a very good start for me (no I have not seen that before).

Good luck. Don't forget to post an image so we can help some more.

I stumbled on Moment of Inspiration (http://moi3d.com/) a couple of days
ago. It's a sort of tablet-geared Sketch-up, but you can use it with a
mouse too. You can draw wiggly things in it. It can export as obj, 3dm and
3ds. The beta has an expiry date, just like POVray 3.7.
