this is a bit tricky, it's hard to increase visibility distance because the view is measured to a certain height. If you want larger vertical distance, you first need to change the measurement code to allow for more spacing. then you can change the onDraw method of TickerView to change the clipping boundaries when it's animating vs. static.
