Hundreds of college students were working around the clock this weekend in a 48-hour Hack-a-thon at Stony Brook University.

Designers, programmers and engineers put their heads together to brainstorm new product ideas. The students came up with a wide variety of projects by creating websites, building robots, and even working on self-driving cars.

"It's totally unique that they get to work on projects that they've come up with and also get help from professional mentors who have jobs full-time in the industry," says Jon Gottfriend, co-founder of Major League Hacking. "And that's incredibly valuable because all of these people here are trying to get their foot in the door with these companies."

On Sunday, students were getting the chance to show their demos to a panel of judges. They have the opportunity to win a $1,500 prize.
