Two years ago Steve and Jared spent a couple days hacking at the Disrupt Hackathon and ended up with GroupMe which went on to great success and an eventual sale to Skype.
For the past 24 hours, developers have been busy hacking away at Pier 94 trying to do the same. The demos will take place at Pier 94 from 11am until roughly 2pm, when the awards will be given out.
If you have a few hours free today and can resist the Party In Prospect Park or some other outdoor event on a beautiful spring day in NYC, you should head over to Pier 94 and check it out. Attendance is free but you do need to register on eventbrite.
