Dynamic Shapes

// build some functions:
var redGradient:Function = sl(16, add(100, mult(5)));

// grid positioning
var xPos:Function = add(50, mult(30, cInt(div(4))));
var yPos:Function = add(50, mult(30, mod(4)));

// create some shapes:
var shapes:Array = createShapes(this, 22, [["beginFill", 0xCCCCCC], ["drawCircle", 0, 0, 10], ["endFill"], ["lineStyle",1, redGradient], ["drawRect", -5, -5, 10, 10]], {x:yPos, y:xPos, rotation:mult(10)});
																 
function createShapes(par:DisplayObjectContainer,  num:Number, 
					                     funcs:Array, props:Object):Array {
	var shapes:Array = [];
	for (var i:int = 0; i<num; i++){
		shapes[i] = par.addChild(new Shape());
		for (var j:int = 0; j<funcs.length; j++) {
			var a:Array = funcs[j].concat();
			for (var k:int = 0; k<a.length; k++){
				if (a[k] is Function){
					a[k] = a[k](i);
				}
			}
			for (var key:String in props){
				var v:* = props[key];
				if (v is Function){
				  shapes[i][key] = v(i);
				}else{
				  shapes[i][key] = v;
				}
			}
			shapes[i].graphics[a[0]].apply(shapes[i].graphics, a.slice(1));
		}
	}
	return shapes;
}

// function building blocks
const F:Function = function(a:*):*{return a};

function cInt(f:Function=null):Function{
	if (f == null) f = F;
	return function(n:Number):Number {
		return int(f(n));
	}
}

function mod(m:Number, f:Function=null):Function{
	if (f == null) f = F;
	return function(n:Number):Number {
		return f(n) % m;
	}
}

function div(d:Number, f:Function=null):Function{
	if (f == null) f = F;
	return function(n:Number):Number {
		return f(n) / d;
	}
}

function mult(scalar:Number, f:Function=null):Function{
	if (f == null) f = F;
	 return function(n:Number):Number {
		return f(n) * scalar;
	}
}

function add(off:Number, f:Function=null):Function{
	 if (f == null) f = F;
	 return function(n:Number):Number {
		return f(n) + off;
	}
}
// shift left
function sl(amount:int, f:Function=null):Function{
	 if (f == null) f = F;
	 return function(n:Number):Number {
		return f(n) << amount
	}
}

This is an unusual snippet I wrote a couple weeks back…. not sure where I was going with this really… has some interesting ideas in it.
