well, following some tutorials, i’m now ready. found an effect and tried to replicate it. here goes…

 
var aD = [];
this.onEnterFrame = function(){
 aD.push(tD = this.createEmptyMovieClip("dot"+(i = (++i > 100000 ? 0 : i)), i));
 tD.idx = aD.length;
 tD._x = tD.tx = _xmouse;
 tD._y = tD.ty = _ymouse;
 n1 = Math.sin((i % 360) * (Math.PI/180));
 n2 = Math.sin(((i+120) % 360) * (Math.PI/180));
 n3 = Math.sin(((i+240) % 360) * (Math.PI/180));
 col = ((0x9F + (0x5F * n1) << 16) | (0x9F + (0x5F * n2) << 8) | (0x9F + (0x5F * n3)));
 tD.lineStyle(14,col,100);
 tD.lineTo(0.5,0);
 tD.onEnterFrame = function(){
  this._x = this.tx + (Math.cos(this.ang += 0.3) * (this.rad++));
  this._y = this.ty + (Math.sin(this.ang) * (this.rad));
  if((this._alpha-=0.85) < 0){
   this._parent.aD.splice(this.idx,1);
   this.removeMovieClip();
  }
 } 
}
