 so, to describe a bit more. the black and green areas are where the map doesn't just spin off to infinity, but keeps returning values. in the black areas, the fractal dimension is very low, so it is possible that the map just returns a small number of points over and over again. in the green areas, the fractal dimension is higher (and highest where the green is lightest). the points with highest dimension probably produce points in a voluminous cloud, or at best a sheet. the darker green areas possibly producing points arranged as lines. so, to describe a bit more. the black and green areas are where the map doesn't just spin off to infinity, but keeps returning values. in the black areas, the fractal dimension is very low, so it is possible that the map just returns a small number of points over and over again. in the green areas, the fractal dimension is higher (and highest where the green is lightest). the points with highest dimension probably produce points in a voluminous cloud, or at best a sheet. the darker green areas possibly producing points arranged as lines.
  
-it would be really interesting to be able to click around on this image and see the attractor that each point represents. i' not sure yet if that will make it into the research or if it will be a future direction.+it would be really interesting to be able to click around on this image and see the attractor that each point represents. i'not sure yet if that will make it into the research or if it will just be listed as a future direction.

 +=== Yet another animation ===

 +Oh, and there is this neat new animation. First some ramblings. I was showing the parameter plots above to Tim Boykett, and he pointed out an important assumption that I was making. The plots are specifically plotting the presence of attractors that just happen to have 0,0,0 in their basin of attraction (because the function doing the escape-plot always uses 0,0,0 as the starting point). To investigate how important this assumption was, I made an animation of parameter plots for changing initial values. The base attractor is the one used in all of the images called "highf" above. At the start of the animation, the initial value used for the parameter plots is -1,0,0, and by the end it is 1,0,0. In the middle of the animation, you should see a frame that looks like highf-c00-01-512esc20.png above (only with the black part filled in white, and rotated 90 degrees counter-clockwise - the renderer has changed a bit) when the initial value hits 0,0,0.

 +(this is here twice because the second one, which is the //right way// to link images with thumbnails, results in a slightly corrupted animation)
