|Baseball fan nirvana!|
Those small green circles are balls, the next two yellow circles are strikes, and the orange circles on the right (which are actually red) are the outs. You can see the score, the inning and who's on base (no one in this image). Plus the pièce de résistance is that the pitch speed doesn't replace any of the balls, strikes, outs or score info -- instead, it temporarily replaces the occupied-bases graphic (the three diamonds).
This is the ultimate TV baseball-score graphic. I snapped this pic from an ESPN broadcast, by the way. Perhaps they have exclusive rights to the design because I'm not seeing it on other networks. I hope it spreads to all of them -- it's that good. And kudos to whoever came up with the design. Excellent work.
