Another weird idea for function visualization. The sketch creates a list of random points, then draws circles around them as a function of the distance from the special point +. You choose the function, though I've preloaded it with some I liked. g is how many pieces the window is divided up into for point placement. (Actually, g in x direction and y direction, so g^2 pieces). dmn is the largest dimension, width or height. N is the number of points. Not sure what to do with this, so if you have ideas, let me know! Did you find a function with a pretty distribution of circles?
