The first POVRay Fractal Raytracing Contest is now open, see
http://astronomy.swin.edu.au/povfrac/
If you have a favourite 3D fractal and ideas on an elegant way
to render it then maybe this contest if for you.

Doesn't this replicate too much IRTC with a topic of "fractals"?
This is mainly because there are practically no limits on what the
user can do (except using external files, which isn't very limiting,
and a maximum of 10000 bytes, which isn't very limiting either).
The problem I see with this is that there's really no challenge
in this competition other than making a beautiful image. Which is
exactly what IRTC is for.
(And of course how to define a "fractal" is another question...)

Nice topic but the competition frequency is quite high, most people will
not be able to invest a serious amount of time that frequently.
The links of the sample images lead to a 404 BTW.

I'm unclear as to why this is a problem/objection.
napolitana replicates margharita with a topping of 'anchovies' - I still like
both ;)

Because there's no challenge. It's boring.

Apart from what you already mentioned i think there are the following
important differences to the IRTC:
- the source code has to be provided
- manipulations in a paint program are not possible
- the images used for voting are guaranteed to be of comparable
technical quality
- the competition is restricted to POV-Ray
While the last point is surely a questionable advantage the other ones
make it quite different from the IRTC and could make it a great
demonstration of the capabilities of POV-Ray.

Granted, this is very different in terms of a challenge from SSC3.
And it is similar to IRTC, on the other hand it is a short time
contest with significant public appeal and plenty of scope for
stimulating images.

Since when this has been allowed in the IRTC?

I have not said anything about this being allowed - i was just talking
about the possibility. In fact this rule has been interpreted quite
loosely recently in the IRTC - all kind of convolution filters are
considered not breaking the rules as well as resizing from a larger
render. If you remove artefacts or do other tweaks in a larger render
and then scale it this is next to impossible to spot in the resulting image.
