I just meant that I'm getting better at controlling the layer parameters with 'Expressions' (a type of java script) and having them create chain events (delayed reactions and so forth). I'm a complete novice when it comes to this kind of programming (otherwise i'd be using something more powerful, like 'processing') but I am getting better all the time with the help of sites like:

thank you
