Instantiate into array : Out of range?

I'd like my enemies to explode into rigidbody pixels on death. The pixels work delightfully once they're instantiated, but I've hung myself up somehow on the instantiation command. I can't figure out why I get an "Array index is out of range" message. The array "points" contains the spots where these pixels will come into being.

 var pixelPrefab : GameObject;
 var points : GameObject[];
 var pixels : GameObject[];
 
 function OnTriggerEnter(other:Collider){
     if (other.tag == "Killzone"){
         for (var i=0;i<points.length;i++){
             pixels[i] = Instantiate(pixelPrefab, points[i].transform.position, points[i].transform.rotation);
         }
         for (var $$anonymous$$tMe : GameObject in pixels){
                 $$anonymous$$tMe.rigidbody.AddExplosionForce(1000,transform.position,0);
             }
         Destroy(gameObject);
     }
 }
