>>Any chance of making the point density adjustable?
Maybe later. Right now you can adjust it by resizing a source image.

>>Any idea what number of curves the original script gave?
If you will load an image 60x60 pixels, you will get 60 curves with 60 points per curve. 500x500 -> 500 curves, 500 points per curve.
If image larger than 600px it will be downscaled automatically.
