L-System, Whirl, and System Requirements
First I'd like to say that I'm very impressed with the level of talent and artistry in the inkscape community. Makes a hobbyist like me feel like a definite poser.
The L-System I really like this feature. I was just using it to draw the the teeth on a gear. I don't fully understand how it works though. Obviously A though F will draw a line forward the specified number of steps. G though L move the cursor without drawing. + and - designate a right and left turn respectively and | (i think it's the pipe symbol) is 180 degree turn.
I am having a hard time with the "[" and "]" that designate remember point on stack and return to point on stack, what's meant by Axiom, and what happens if an X or Y is thrown into the function definition.
Also, does anyone know a good page/reference for most of the famous fractals?
Whirl Whirl also has me a little stumped. I would think that x,y coordinate specified in the dialog would define the axis of rotation. I've tried several times to make an object whirl around it's center of mass/symmetry without any luck. I've use the points designated by the selection dialog which didn't seem to work. I'm guessing it's one of the corners of the bounding box. The I tried putting guides through what I thought was the center and using those values. No luck there either.
My System My system seems to get really bogged down when ever I have any significant amount of nodes/objects for inkscape to keep track of. I'm running Windows XP with a 2.4 GHz Celeron and 640 MB of ram. I think this is going to become a significant source of headaches for me in the near future. I want to upgrade. Thoughts about minimum requirements for working comfortably on a Mac? I was thinking of trying a Linux system, but decided against it after installing Fedora Core 6 on my PC. I ran into too many compatibility issues with modems, monitor, printers, and other input devices. But, that's a discussion for another forum.
Thanks for some great software. I hope I can contribute in the project in the near future.

There is a new Gear effect added to SVN. It will work with Inkscape 0.45.1 (and maybe earlier versions). You can get it from SVN or from my book's website:

Have you looked at the Wikipedia page?

Which version of Inkscape are you using? In 0.45.1 the coordinate system of many of the effects is upside down. In other words, the (0,0) coordinate is at the top left of the page. A little math will get you the "correct" Center Y (Y = page height - y). In SVN the effect has been changes so that the center of view is used.

Gears works in 0.44 as well, BTW.
Has anyone documented what it would take to convert extensions like this into editable parametric shapes like Stars or Spirals? Being able to edit the parameters with a realtime display of the result would be very nice, and being able to do this via extensions instead of having to build it into the core would be nicer still.

The best ones I could find are shown here:
