Watching a couple of pros like TFC players Eric Avila, Oscar Cordon & Keith Makubuya juggle a ball can be fun. Standing in the middle of their circle would be better. And being able to stand in the middle of the circle without getting nailed by the ball is best.
Check out this cool, interactive clip shot last week during some downtime at the Disney tournament. Use your mouse to turn the camera 360 degrees and follow the boucing ball. Fun stuff.
