Heres my attempt, leave it running and go have a coffee or something

code:


_root.createEmptyMovieClip("lor",1);

var scaler = 10;



function lorenz(h, a, b, c, x0, y0, z0, N, rad){

	i=0;

	lor.clear();

	_root.onEnterFrame = function(){

		x0 = x0 + h * a * (y0 - x0);

       	y0 = y0 + h * (x0 * (b - z0) - y0);

      	z0 = z0 + h * (x0 * y0 - c * z0);

		if (i == 750){

			lor.moveTo((x0 * scaler) + (z0 * scaler),(y0 * scaler) + (z0 * scaler))

		}

		if (i > 750){

			R = (255*(i/N)).toString(16);

			G = "00";

			B = (255*(i/N)).toString(16);

			col = "0x" + R + G + B;

			trace((i/N) + " / " + col);

			lor.lineStyle(0,col,100);

			lor.lineTo((x0 * scaler) + (z0 * scaler),(y0 * scaler) + (z0 * scaler));

		}

		if (i++ == N) {

			delete this.onEnterFrame;

		}

	}

}

lorenz(0.001099, 10, 28, 8/3, 1, 1, 1, 20000, 0.04);
