Trangleball - Sport of the Future?

Last month when Gothamist was in Coney Island for opening day, we spotted a perplexing activity taking place on the beach. A few people were throwing balls at what seemed like a wooden triangle in the middle of some tubes laid out in a circle. After closer inspection (like reading the sign), we found that this bizarre game was called Trangleball. Essentially, the game involves throwing a ball off the center triangle and your opponent has to try and catch it. If they don't, you get a point.

Perhaps the future is now? Or is it never? We're not quite sure. But it does look fun and easy to set up.
