We realized a 15 minutes animation that shows some of the properties of the
well-known Penrose tessellation.  It is entirely realized using POV-Ray.
It was quite a challenge; however we think that the final result was worth
the effort.
From the home page "http://penrose.dmf.unicatt.it/" it is possible to
download the matroska version (1280x720) of the animation, available in
Italian and English.

An excellent animation, very impressive in the subject matter and the 
use of PovRay. I particularly enjoyed your choice of background music 
and sound effects (also when you chose not to use them).
How long did the project take?

  That was certainly interesting.

  (I just wish people stopped using the default marble texture for this
kind of animation... POV-Ray can create much more awesome textures than
that.)

For the sound effects I used "www.findsounds.com"; you need a little
imagination: e.g. the sound when we impose the adjacency constraints is
an "uncorking" sound.

There are not many sounds, the major reason is laziness...
The background music was originally the "Variations on a rococo team"
by Chaikovsky, we changed to "Ambient Symphony" by "zero-project" in
order to avoid license problems.  Some pieces where slightly adapted
(with audacity) to the needs of the animation.

Roghly one year and a half, not full time, but it required
*a lot* of time in any case.

Thank you for your interest.

Well... sorry for that!  We are really novice to the use of POV-Ray, so
we just stuck to the textures provided in the default povray library and I
beg your pardon if our choices were naive.
Do you have an alternative suggestion?  (Although I really don't know
if we will spend the effort of recomputing all the frames!)

You kept it simple which is a good thing and the sound effects were 
evocative of what was happening on the screen.

No, restraint. ;-)

I recognised Tchaikovsky but could not place the actual piece. :-D

Well done it fitted in very well.

have a mathematical subject is quite impressive too.

Yes, and that wonderful animation was perhaps the strongest motivation to
start our work.  Actually Jos Leys is the one that suggested me to post in
this newsgroup.

Really awesome!!! What came first: the music (and then the video matching
the music) or the other way round?

I think that the music came first. You can read the thread here.
