I think when the MLB.tv Mosaic feature first came out, I tried it out some and messed around with it and stuff.  I ended up taking a screen grab of it, and I think the reason will be obvious below.  I just kinda stumbled across this thing while looking at my stash of Mariner wire photos from last season.  

For the record, I thought I'd saved another one where the alert was that Sandfrog was at the plate.  It's great stuff.
