## The Code

Most of the code hangs on the light source:

```onClipEvent(load) {

this._x=414.0;
this._y=198.0;

// a * 3 is radius of circle -----
a = 59;
i = 0;
_root.ratio=50;

// x base & y base (in stead of 0,0)
xb = 198.0;
yb = 198.0;

function SinMouseX(AngleX) {
return Math.cos(Math.PI/180 * (_root.DgrMouseX - AngleX));
}

function AlphaMouseX(Z,X) {
return ((_root.DgrMouseZ/Z) * _root.ratio + X * (100 - _root.ratio));
}

}

onClipEvent(enterFrame) {

// making the light move -----
i++;
if (i >= 360) { i=i - 360 }
// must be in radians (not degrees)
// -------------------------------

// path of lightsource -----------
if (_root.lightsource == "manual") {

xm = _root._xmouse;
ym = _root._ymouse;

} else if (_root.lightsource == "automatic"){

xm = xb + (2 * a * Math.cos(theta) + a * Math.cos(2 * theta));
ym = yb + (2 * a * Math.sin(theta) - a * Math.sin(2 * theta));
}
// -------------------------------

// pythagoras for angle mouse & x,ybase
xt= xm - xb;
yt= ym - yb;

_root.DeltaX=Math.sqrt(xt * xt + yt * yt);
// -------------------------------

// z is angle upwards: x,ybase -> light = radius = 180

// -------------------------------

// recompute flash-angles to normal-angles
if(xt < 0 && yt > 0){
_root.DgrMouseX += 270;
} else if(xt < 0 && yt <= 0){
_root.DgrMouseX += 270;
} else if(xt >= 0 && yt <= 0){
_root.DgrMouseX += 90;
} else if(xt >= 0 && yt >= 0){
_root.DgrMouseX += 90;
}
// -------------------------------

}```

This is the code on the facets:

```onClipEvent(load) {

// angle of this facet -----------
FacetZ=45;
FacetX=63.75;
}

onClipEvent(enterFrame) {

XTemp=_root.light.SinMouseX(FacetX);

// set alpha
this._alpha = _root.light.AlphaMouseX(FacetZ,XTemp);

}```

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
