i was reading another thread about bitmapdata, and i saw something like this:  
[http://img170.imageshack.us/my.php?image=vectorwarszh4.swf](http://img170.imageshack.us/my.php?image=vectorwarszh4.swf)

i thought it was very cool how when everything moves in the game it leaves a blurry trail behind. But, i am unsure how to do this. obviously with bitmapdata, and filters… i’m not exactly sure what to do.

lets say i start with a movieclip from my library

```auto

var box:Box = new Box();
var filter:BlurFilter = new BlurFilter(6,6);
box.filters = [filter];
//...then what?

```

i’m not even sure if that’s right… what do i do?
