Hey guys, I'm the founder of WeHack.It, a website to connect developers all around the world through online hackathons.
next weekend we're launching our second real-time hackathon. The challenge is this: you have 8 hours to create a cool app from scratch using jQuery/HTML5. It can do whatever you want (canvas, sound, imaging, crowling, etc.)
the hackathon starts this Saturday (March, 3rd), more info on dates, prizes and rules here:
