This Scrippy creates some stunning results when you use graphics in place of the solid colored sliders I've used.  I'm using plain colors so it will be easier for you to see how it was created. 

First create a container to hold the butterfly image and all four slider containers.

To create this type of Scrippy,  you need to use an image that has a width that can be evenly divided.   The butterfly image is 444x293 pixels.  Since I wanted 4 sliders, I divided 444 by 4, which equals 111 pixels.  Then I created 4 positioned containers sized 111x293 pixels.  The graphics I used for each scroll are also 111x293 pixels.  

The containers are all positioned from the left and set right next to each other.  The first container is set at 0 pixels from the left.  The 2nd, 3rd, and 4th containers are set at 111, 222, and 333 pixels respectively from the left.  Review the Horizontal Layout settings for each container.

Next,  2 positioned scrolls are inserted into each container, scrolling in opposite direction.  The space between setting for each container is set at twice the width of the graphic used, in this case that would be 222 pixels.  Make sure the speed is set at the same for all 8 positioned scrolls.
