Made with Apophysis, lots of fun when you run out of real images to play with...

and my favorite from this group:

Thos are really nifty, Tim. I've got to try playing with apophysis when I've got some time.

Neatly sidesteps the battles between MF and 35, or between Canon and Nikon, too.

Sometimes when I want to stretch a 4x3 image to 5x3, I'll copy a couple hundred pixel vertical strip off each side, do a mirror image, then paste onto the side of the original.  When I do this, I see patterns at the join points that look similar to the images here.  in those cases of course, additional work is needed to remove the pattern effects.  So I don't know whether the symmetries of the copy-and-paste patterns have anything to do with the topography of fractals, but patterning issues vis-a-vis the apparent randomness in a natural scene are things that take up lots of time when editing digital photos.

Some of mine: http://www3.telus.net/wolfnowl/Fractals/index.html
Some of Marcia's: http://www3.telus.net/wolfnowl/Marcia/index.html

They can be a lot of fun, but also a great way to lose track of time!

I particularly like the style in Deep Space and Emerging Into Being - great palette (gradient).

Did you know that 2.8 beta is available from source - seems a bit smoother and the transform window seems a bit better behaved (at least with my graphics tablet)  Some other functionality - eg: invisible transform - the transform impacts the other transforms, but isn't represented graphically itself, no idea how to make use of that.

In any event, you're right, a great time waster...

Cool stuff, Tim!  I used to love playing with a Spirograph when I was a kid.  This is a Spirograph for adults!

Don't kid yourself, Lisa... It's really all math - complex formulae, reiterations of compression of numbers... they just happen to look really cool, but that's not the intent.  Really!

Thanks, Tim.  I'll check out the new version.  I don't know that I have a 'favourite' of the fractals I've done, although a friend of mine has asked to use this one for her business.

I have a hard time looking at this one for more than a few seconds or my eyes start to spiral.

Not that complicated really:

[a href=\"http://en.wikipedia.org/wiki/Fractal]http://en.wikipedia.org/wiki/Fractal[/url]

And, a bit more technical, but what you were probably referring to:

http://en.wikipedia.org/wiki/Iterated_function_system

Simply put, it is simply a figure drawn from computing the coordinates of a point iteratively from the coordinates of the previous point. The formula used determines the shape. Colors can be computed in different ways but follow the same idea.

Since most fractals are 2D, it is convenient to use the complex number paradigm to manipulate the coordinates of the points, along with the mathematical rules associated with them.

By the way, any good fractal software on the Mac?

Cheers,
Bernard

I have fond memories for the spriograph as well...  Perhaps more of a "strange attractor" than a fractal

I loved my Spirograph.  They're still around, but very hard to find.  I used to play with set squares, compass, French curves and graph paper as well, but nothing that could really be called a fractal.  I remember when I took my first programming courses how excited I was to discover that complex graphics could easily be created using a pen plotter and some simple geometry equations.
