In a class on sport performance, my coach introduced a training tool for reaction time, depth perception and coordination. The "Reaction Ball" is a oddly shaped ball that bounces in an unpredictable direction. Catching the ball requires not only fast hands but also the ability to move your base so that your hands are close enough to do the catching.

In my experience the reaction balls are both fun and frustrating because of their unpredictability. But the training rewards are certainly worth the effort!
