It is good you show your working code, but perhaps you can show also a version of one of your attempt to add a special effect: it will show us what kind of stuff you want to do, and perhaps you are close of the solution with just a little blopper stopping it from working, which might be easy to fix. Or at least, it will give us some concrete direction to give advices.
