to replace the mouse with your own cursor, use this code for your movieclip cursor.

onClipEvent(enterFrame){
Mouse.hide();
this._x = _root._xmouse;
this._y = _root._ymouse;
}

for the color, i would suggest using two cursors - one that is on top of the other. so the stationary color (green) is on top of the other color. then fade the alpha of the top one however you like.

i use this site for tutorials... admittedly i've never looked at flashkit's tutorials, they might be better.

and i've never tried doing a blurring effect like that.
