Hi, I have a question about this future (star?) tool: could it be used to generate graphics of the same complexity as the one in the attachment? It would be really awesome to have an Open Source software capable of generating that kind of security design, used on cheques, diplomas, and other important papers.
Not quite the same as graphics of the original message but very security like:
Take star tool. Set "Corners" to a large number (i.e. 51). Set "Rounded" to 0.25. Drag Base handle to other side of star.
Another alternative is to use the Tile Clones dialog with an offset center of rotation, see:
http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Tiles-Tricks.html
It would be nice if the Tile Clones dialog had some option to allow one to take an object or group and create clones rotated around an arbitrary point (like the Rotation center handle). Perhaps a button on the Rotation tab that would specify that the Rotation center handle be used and that the Shift in X be set to -100% for columns and Shift in Y set to -100% for rows.
Examples of both are in the attached Inkscape SVGZ file.
Actually it reminds me this tool: http://www.oberonplace.com/products/securidesign/index.htm
Page won't load for me.
Thanks! Molumen

Hello Bryce,
I have posted 12 screen shots of increasing complexity here:

Sliders modify control point lengths and angles (Mirror, Twist, CP1 and CP2). These are calculated from the turning angle of the turtle. Control point length default is 0.33333 * last distance travelled.
My other 2D version is a HyperCard stack written back in the early 1992. This outputs PostScript (Adobe Illustrator 3 file). It generates a host of other shapes (cogs, spirals, shells etc) and uses the same principle of "live" shapes, generated procedurally.
I have a 3D Nurbs version in C++ that works around spherical polyhedra but it's about seven years since I wrote the code and I'm still trying to untangle what I actually did :)
Cool, that's really sweet. This looks similar in some ways to our star tool, but I like how much more 'spirography' this looks. Are you interested in implementing this (and/or the cogs/spirals/shells into Inkscape?)
Like bulia, I also wonder if this could be folded into the current star tool, to make it more powerful? If not, a new shape could be added, but that could be a lot more work. In any case, I'd be happy to give pointers for getting into the codebase if you'd like.
