Superheroes in Union Square

Have you ever noticed while transferring from the L to the 4/5/6 train at Union Square that there is a video projector for advertising? Asics, the official sponsor of the New York marathon, buys most of the ad space in Union Square subway station during the month of October. This year they added a nice interactive element that allowed commuters to throw fireballs by detecting their motion. It certainity kept us busy for a few minutes but I am not sure how many pairs of Asics we are going to buy though.
