This is my first animation posted here (IIRC).
Tek suggested that I should animate this shape:
http://news.povray.org/povray.binaries.images/31187/
- and so I did.
I used some quadrivariate NURBS functions to
deform a cube formed by many smaller cubes built
from meshes, cylinders and spheres.
A quadrivariate function takes 4 arguments. In
this animation time is used as the 4th argument:
U, V, W, T
By doing it this way, I only had to provide some
"key-frames" (8 for this animations). The script
then "interpolates" the shape smoothly between
these "frames".
Thanks to Ingo for tipping me about the TMPGEnc
MPEG encoder.

I like it, it animates very well. The color scheme is just right too.

Ow my eyes! I like it :)
Could you make it change the parameters more smoothly? I recommend putting all
the parameters on sine waves, that's what I do!

woooot simply a m a z i n g
it's eyecatching work, but i think when you use a sine function movement it
will loose much of its effect
but why not try it ;-)

Agreed.... and more frames so it moves a bit slower and make the animation
somewhat......longer!
