Creating Static TV Noise in Flash using AS3

Creating Fast and Smooth Static TV Noise in Flash using AS3 was a simpler task than I expected it. First attempt was using for loops to set every pixel and was not very fast. A Simple browse through the API docs for BitmapData class gave me the 'noise' method

bgdata.noise(Math.random() * 1000, 0, 255, 7, true);
did the trick :)

Complete code below

package {
import flash.display.Sprite;
import flash.display.Graphics;
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.geom.Point;
public class StaticNoise extends Sprite {
const ww = 480;
const hh = 272;
var bgdata:BitmapData = new BitmapData(ww, hh, false, 0xffffff);
var bg:Bitmap = new Bitmap(bgdata);
var zeroPt:Point = new Point(0,0);
public function StaticNoise() {
addEventListener(Event.ENTER_FRAME, drawBaby);
function drawBaby(e:Event) {
bgdata.noise(Math.random() * 1000, 0, 255, 7, true);

You can modify,use this code where ever you want, without giving credits. But please just let me know in the comments if it helped you.
