Using the drawing API in the Flash Player we have a simple bit of script that generates lines in random directions, or random color and thickness and occasionally a curve as well.
A usual the actionscript I implement in this script will not play in the internaly Swishmax player, as it is built on the Flash Player 4. The latest Flash Player 5+ should play this without any of the actionscript issues you will see in the internal Swishmax player.
