IBM performs a bunch of analytics on social media data and presents the results on the Interactive Wall. Here, you can see the relative percentage of positive tweets versus negative tweets for Serena Williams.
One cool feature of the Interactive Wall allows you to spin a tennis ball globe and see which of the world's top 20 men and women tennis players live in a specific country. Here, I tapped in Serbia's flag to get info on Novak Djokovic and Janko Tipsarevic.
The Mets/Willets Point station on the #7 line of the NYC Subway serves Flushing Meadows directly, stopping right in between the Mets' Citi Field Stadium and the USTA Tennis Center. I don't know how they did it, but somehow IBM's Interactive Wall can estimate the time until arrival of the next Manhattan-bound train.
