Jquery Help

I was thinking about making a query image slider plugin. I know how to code up a simple image slider however i have noticed that the image sliders that sell these days have fancy effects. I was wondering if anyone could tell me how these effects are achieved or where I could learn. I am talking about the effects similar to the ones that come with Nivo Slider. Specifically the box splice effect
