I love the idea. I would like to use it in an animation, where the light
rotates, and the shadow suddently turns into something recognizable.

"put your hand up if you never put your hand up" - I think there might be a
problem here....

Nice - I played with something similiar (a shadow sig), but never finished it.
It's a shame the pigment on the blocks is so bright - why not try:
pigment{rgb D}
instead of:
pigment{rgb P}

Nice - are you using Rune's particle system on the fountains, etc.?

I suppose there are quite a lot of people who read these groups but don't
post.  And AFAIK the newsserver access statistics also indicate this.  The
number of POV-Ray users not using these newsgroups at all is probably a
lot higher.

And without the intention to discourage anyone to post here i think this
also has its positive effects.  If every POV-Ray user would ask all the
questions occuring to him in these groups (like some do ;-)) it would
become extremely difficult to maintain an open eye to those questions
really requiring some discussion within the lot of things that simply
could be answered by reading the manual or the FAQ.

I don't consider myself an experienced POVer, but it is a fun hobby.  I
mostly lurk here, trying to collect useful tips.

Nice.  How do you people come up with recursive functions like that (and
the shortest code contest - did they ever post the code for the second
one?)

  My problem is a bit the opposite: I write too much and don't read
enough. :P

You are right, POVers are an excellent community. I read these forums a lot,
but as I am just learning POV my questions are fairly basic. I find that
usually I can just search for it and someone has already posted something
similar that gets me going. Only once did I actually ask a question, but it
was answered within an hour.

Sorry, I haven't gotten into the signatures yet... I'll have to try some.

I was hoping that it would be a problem, otherwise the news server would be
swamped with replys. :-)

Too dark for me.

No, I did the macros for the fountain and the trees myself. I like to
reinvent the wheel. I think one learns more by doing it oneself. And
afterwards you can say that it is completely yours.

You should start a group called Dumb Questions, where anybody could ask how
to get their media or radiosity to work, without comments like "Read the
doc.". The problem is to get people to post there and not to the
advanced-users group. :->
