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... :)

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

Ah, excellent point - here are the source attractors for the morph.

This morning I found this morph animation in a subfolder of my attractors
folder; I had completely forgotten about it! Originally rendered as an 1920x1080
(HD) AVI, I just squashed it down into this little MPEG-4 to post here.

That's fascinating! I take it these two attractors use the same set of
equations? It looks like it - there appears to be a certain congruence between
some of the features (if that's the right phrase!).
I've got to try this!

I like them all.
A worthy tribute to chaos theory.
