Rect vs Ellipse

for (var i:int = 0; i<100; i++){
	graphics.lineStyle(0,0);
	graphics[["drawEllipse", "drawRect"][int(Math.random()*2)]](Math.random()*400, Math.random()*300, Math.random()*100,Math.random()*100)
}

And a more readable version:

var methodChoices:Array = ["drawEllipse", "drawRect"];
var method:String;
var xp:Number, yp:Number, w:Number, h:Number;
for (var i:int = 0; i<100; i++){
	method = methodChoices[int(Math.random()*methodChoices.length)];
	graphics.lineStyle(0,0);
	xp = Math.random()*400;
	yp = Math.random()*300;
	w = Math.random()*100; 
	h = Math.random()*100;
	graphics[method](xp, yp, w, h)
}

Here I use yesterdays associative array function call technique to do something different. Not really all that useful, but interesting….
