Having a ball of a time

This bedside alarm clock that you see might look pretty run-of-the-mill, but it actually stands out from the crowd with a metallic sphere located on top that is used to select which radio station you want to listen to. Although the stations are programmed via the conventional method, switching them is a whole new ball game (pun not intended) – all you need to do is roll the ball into one of the nine indentations located on top and you’re good to go. I wonder what happens when you lose the ball – can you replace it with something else? The Memory Ball and Alarm Radio retails for $60.
