Sounds like a rounding error, and it's a little different from what I was talking about. Did you look at fltree.pdf? If you draw L-system lines as rectangles, and put the centers of the short sides of the rectangles in the same place when the lines they represent are coterminal, then when the lines are at a bit of an angle to one another, the short sides of the rectangles representing them will have the supplement of that angle between them. It makes it look like somebody's been trying to chop down the tree, and is about half done. PostScript has ways of handling this, but they don't work for lines that change width and branch. LParser seems to have a solution.

My idea was to showcase coloring methods by having everyone render the same 3 fractals (a Mandelbrot zoom, one Julia with a "lake" and one Julia dust). This would show methods that work better for interior areas, exterior areas, and any that may work better on Mandelbrots than Julias (or vice versa).

This would show methods that work better for interior Julia sets from points inside the Mandelbrot set have a single continuous "lake", much like the Mandelbrot lake, with a nonzero area. Julia sets from points outside the Mandelbrot set contain only single isolated points, known as a Cantor dust. btw: someone told me Cantor dusts have aleph-one points in them. It seems to me that they should be aleph-null, because if you're constructing a Cantor dust in the traditional way (take an interval, cut out the middle and take the intervals on the ends, repeat) the only points that remain in the dust are the points at the boundaries of the intervals you take, and you first encounter each one of them at some integer-numbered subdivision step, and you encounter only an integer number of points at each subdivision step, so each point in the eventual Cantor dust has some ordinal number at which it becomes a boundary of an interval. Am I missing something?
