Hey Dennis, maybe the fullscreen slider addon is what you are looking for? http://laytheme.com/fullscreen-slider.html
But the fullscreenslider is not exactly the same as the smartscroll that you sent me.
You could probably also make that smartscroll script work with lay theme if you know some javascript. You could make the rows of a lay theme project to initialize the smartscroll script on. Here's some info about how to use js with lay theme: http://laytheme.com/documentation.html#custom-javascript
