Sophisticated list item

Hi everybody,

I would like to create an animation in grasshopper using a single slider.

In Red is the effect I would like to get using a single slider.

For the moment I only manged to do it using the component "Serie"(second picture). But once, the slider arrives at 39, all the items become visible.

I would like to tell him to restart the entire serie when it arrives at its end and to someting like 0-39-0-39...

Would it be possible to get a slider that creates and "endless effect" (in the serie) as it occurs with the item list component ?
Thank you !
