more spirally goodness.  
click to generate a new one, then click again to make another, etc…

\*edit - much improved version here: [http://www.kirupa.com/forum/attachment.php?attachmentid=32647&d=1137412554](http://www.kirupa.com/forum/attachment.php?attachmentid=32647&d=1137412554)

```auto

var randomNum = function (Min, Max) {
	return Min+random(((Max+1)-Min));
};
var myRefArray = [];
var HH=this.createEmptyMovieClip("HH", this.getNextHighestDepth());
HH._x = HH._y=200;
onMouseDown = function () {
	startRotate(randomNum(-30, 60), randomNum(-100, 100), 0, randomNum(60, 600));
};
startRotate = function(aaa, bbb, c, scl) {
	for (var p = 0; p<30; p++) {

		var aHH = HH.createEmptyMovieClip("aHH", 300+p);
		var cHH = aHH.createEmptyMovieClip("cHH", 2000+p);
		var eHH = cHH.createEmptyMovieClip("eHH", this.getNextHighestDepth()+1);
		eHH.lineStyle(0.8, 0xFFFFFF, (6*p)+10);

can someone check if i’m meeting the \<=25 lines requirement? i think i’m counting this right, but i hope i’m not over.
