Please comment and critique! If no one criticizes me I won't improve .

COMPATIBILITY UPDATE:
-So I thought these were PS 7.0 compatible; apparently not, since PS 7 refuses to load them. WTF Adobe, why are brushes not backwards compatible?

COMPATIBILITY INFORMATION:
-Photoshop Creative Suite 4 and up
-GNU Image Manipulation Program v2.6 and up

Wanted fractal brushes but could never be bothered to make any? Here are 180 strange attractor fractals in .ABR format for your unlimited noncommercial use .

(If you plan to use them, please remember to link back because it helps motivate me make more ^^. Anyone planning to use this for commercial use (like that'll ever happen) should contact me for permission first. )

Brush sizes are typically between 500 and 800. Downscaling causes very little quality loss.

FAQ:
What was used to create the brushes?
Chaoscope; I rendered the attractors in Gas mode.

How do I use these things? O.o
Lighting, effects, backdrop image, smoke effect, whatever you can think of. These are pretty flexible brushes; their usage quality depends on the user.

Why didn't you compress it?!
In the time it takes for you to uncompress the thing you would have already downloaded the 8 extra MB. Mostly just my pet peeve of hating unnecessarily compressed files on DA. (It *is* more convenient to just save the .abr directly, IMO.)

But I have dial-up!
LOLwut.

Why are there so few Pickover and Unravel brushes?
I found them to be quite visually unappealing and most of them looked the same: chaotic and unusable as brushes. The ones I have are the rare few stable ones.

Why no Julia sets? :C
Have you seen quaternion Julia sets? They're really, really ugly when flattened like this, and take forever to render. I would rather take their 2D counterparts.

No Rossler attractors, either! How could you?!
>_> <_<

Some of your brushes are too light/dark! Why?
Because.

Hurr?
Durr.

Thank you for visiting and please comment! It helps me to know what types of fractals are useful as brushes . If you make anything with these please do drop a message! It's nice to see how they are being put to use.
