I've seen one made out from an old ploter converted with the laser from
an old fax machine. You can also reuse one from any old laser printer.
It could create stuning models out of ordinary sugar with a granyness of
about 0.5mm.
It can be home made for under $100 or about, and the functioning cost is
prety low.

I've seen demos of that as well. In one instance, they "printed" a
chain made out of sugar, with the links already connected.
The raw materials are very cheap. It's a fast-moving field of research
and development. Very exciting stuff. In another 10 years, we might
have machine to fabricate 3D objects out of all kinds of materials,
including food!
Imagine the possibilities:
Strange Attractor Crackers
Chocolate Mandelbulbs
Menger Sponge Cake
Cantor Cheese Logs
Moebius Strip Steaks
Solenoid Licorice
(see http://www.dgp.toronto.edu/~mjmcguff/codeGallery/*)

They didn't teach anything like that when I was in school, although I
still didn't pay enough attention.
My mind managed to completely block out all memories of differential
equations completely. To this day I couldn't tell you the first thing
about them. :-)
But thanks to POV-Ray, I'm very comfortable with trigonometry!

I'm sure I would have paid a lot more attention if they had used POV to try to
teach me (although I don't think it was around back then...). Still, my daughter
was the only pupil in her class that knew what a radius was as she had asked me
how I created pictures on the computer and I had shown her how to make a very
basic scene. I'm sure using something like POV would make the lessons much more
memorable.

Wow, those are awesome Bill! I wrote a little app a couple of years back to plot
2d attractors but never came up with anything as cool as your 3d versions. The
renders are very artistically done - I love the lighting.
Seeing these made me go searching through my own stuff - here's one I did that's
a "morph" between two attractors. I loaded the data sets into SDL arrays and
used elements from each array as cylinder endpoints (with gradient pigments
along their arbitrary axes). Good times.

And here's another one where I used the attractor data to generate a height
field and associated pigment.

Random colours and positions, seeded by the data file. Usually needs a bit of a
tweak to get a nice combo, but quite handy!

Looks interesting - it's a pity you can't quite make out the attractors'
shapes... good idea though. I might try an animation using my sphere technique,
if I turn off AA they only take a minute or so.

Gobsmackingly goodlooking!
But I think you got the spidery one wrong: looks more like a butterfly and a
very good looking one at that!
Povray abstracts at its best, ladies and gentleman! :D

Hehe, naming was an issue, until I decided to call them the first noun that came
to mind when looking at the 2D plot. Some of them look utterly different in
3D... :)
> Povray abstracts at its best, ladies and gentleman! :D
There's plenty more. I'll put them all up on a web page at some point :)

What a good idea to use that background. :D
