I'm currently at work on the first Batting Explorer, an interactive tool where viewers can filter season level batting stats using more than 25 different filters. This project is being built using the great Exhibit tool, currently housed at simile-widgets.org. Within the Collections page on this site, you can find more than 50 game level explorers built using Exhibit; it is a pretty remarkable tool to work with, and I see more future use for it on this site.
Obviously, once the batting series is complete, I'll feel the urge to do a pitching series along the same lines, followed by whatever seems compelling at some future date.
As soon as the Batting Explorer is launched, I'll try to follow with a video tutorial to illustrate all the possibilities, but it is also easy to just jump in and start playing with all the filters to get a sense for the power that Exhibit provides.
