Watching one of these live just brings home exactly how low activity a baseball match is. You can easily miss a pitch if you're not actively watching it and keep your attention span on it. It also brings to mind how much the commentary during a game keeps the viewer engaged. Live video and a good director cutting to different cameras also helps. Radio with out the color would be insanely boring:
Here's the pitch, low and outside.Ball 1.
30 secs of silence.
Here's the pitch, fast ball down the middle. Swing and a miss. Count is now 1-1.
30 secs of silence.
Have some ideas on how to make this a bit more engaging for baseball, still. But ultimately it isn't really made for active viewing or to replace a live broadcast. I think of this more for the fan who wants to keep it on in the background or on the TV while they work or multitask.
It would certainly be fun to attempt it. You might have to mix in some pre-defined animations for "run up the middle", that could do minimal updates like Jersey numbers.
