Thanks!

I first tried breaking up the motion up into several #if blocks and control
the individual motions with math functions like cos(), sin() and pow(). But
that looked way too stiff, so I ended up just using two splines, one for
rotation and one for position.

Oh yeah, lots of magic things do. Farries (probably originating from Peter
Pan), magic wands, and, well, this magic lamp does too!

Hmm, I feel sorry for the people in that spacecraft! ;)

This one using textured discs?
http://news.povray.org/povray.binaries.animations/20340/

Or these using MegaPov glows?
http://news.povray.org/povray.binaries.animations/15165/
http://news.povray.org/povray.binaries.animations/15170/


I really miss the ability to use glows. Media just don't produce nearly as
nice effects. :(
The thing about glows is that even small glows affect the image a little bit
in a very large radius (infinite radius actually), and that way multiple
small glows become a bigger glow. Doing that with media would be extremely
slow, so instead I just use small media glows that don't interact very well
and don't have the same glowing look. Glows wouldn't have worked well here,
though, as they become invisible on backgrounds that are not dark.

I'll see how this animation looks with textured discs - maybe better than
how it currently looks.

That's pixies. Faeries (or fairies if you like) don't glow. Or sparkle.
Or have ickle wings. Or... etc

Ooops, I forgot to mention how wonderful you are, and how we all want to
be you when we grow up and/or have your children.

*loool*
this lamp movie is really lovely.

How did you define the path for it? It moves really well and smoothly.
Hopping and swirling around and GOOOOoooooo...... *g*

I was never aware of the distinction and didn't know the word "pixie" as no
corresponding word exist in my language AFAIK. Could you describe the
difference between fairies and pixies? And what does "ickle" mean?

One spline for rotation and one for location. I've posted the source code of
the animation (not including the particles) to povray.binaries.scene-files
in case you're interested.

Yes, this is the one. The particles have a more "magical" feel when they look
like this.
