Since everybody is so captivated by this [not!], I'm going to just come
out with it now.
You remember the chaos pendulum? A metal weight suspended over three
magnets. A while back I make a simulation of its path.
Well, this is 102,400 chaos pendulums, all running in parallel, but each
one started from a different initial pixel location. And each pixel is
coloured according to how close its pendulum currently is to each of the
three magnets. (The magnets are red, green and blue.) If you watch the
animation, it appears to "pulsate" due to the typical swing period of
the pendulum.
In this simulation, there is no gravity, no dissapation, and the magnets
produce linear forces. I plan to try quadratic forces next, and maybe
add some gravity. I'm expecting to find quadratic force makes the
patterns a lot more complex...
BTW, I have done animations with other colourings. Best of all was a
sky-like agate pattern that morphs to the swing. But it keeps crashing
POV-Ray. :'{

Very interesting that you use POV-Ray for research, so it looks really
useful. Very nice graphics to represent your data.

Ouch - no wonder I was totally wrong. Never heard of a chaos pendulum - some
kind of classical experiment or device in physics?

Like I said, a pendulum with a magnetic weight, with three magnets
placed near to the swing path. You can find them in places like the
Discovery story and the Gadget shop - along with Netwon's Cradle and
other such amusements...

Hmm... what's that "plasma ball" thing called? You know, the one with the
glass sphere, filled with some gas (no idea what) and when you place your
hands on it it seems to "flow" in your direction, looking like lightning is
going on inside it? Some kinda flourescent gas.

That would be: a plasma ball.

Now as he walked by the sea of Galilee, he saw Simon and Andrew his
brother casting a spam into the net: for they were phishers. And Jesus
said unto them, Come ye after me, and I will make you to become phishers
of men. And straightway they forsook their nets, and followed him.

Har har har...
Yeah, "plasma ball" seems descriptive, but I was thinking it had some
cool-sounding scientific name...

What, like "plasma ball"? I don't know about you, but to me "plasma"
sounds both cool and scientific. IIRC, the ball is filled with very
rarefied gas -- somewhat like a plasma. :->

Plasma globe. Usually (the typical blue tendrils, orange footprints
variety) filled with Ne and He in a vacuum (mostly He. The bit of Ne.
gives the footprint the orange glow)
I actually own one of these. 8-)

Me also. (The footprints are pink.)
I also own a second one - it's really weird. The surface is the glass is
opaque, but when it's on you see randow colours glowing through it. (I
imagine the glass itself is coated with some kind of phosphore - the
colour seem to stay on one side of the globe...)
I think the contents of the globe might actually count as "plasma" too...
