Mission 7 - Personal Billboard
Spicy Remix 3A
This remix uses two lists for A and B. The first list is images, but
it can be anything. The second list is a mix but again can be anything.
Both lists should have the same number of items.
-It also includes the button to break the loop and end the program-
