Developers built all kinds of apps covering a wide range of topics— from games and music to cooking to philanthropy. We saw some incredibly creative hacks – including projects incorporating hardware elements like an Arduino and a clothes iron – and can't wait to see what you come up with next.

We're pleased to announce the Grand Prize winners, whose projects stood out from the many high quality apps. These teams have won a trip to Facebook headquarters in Menlo Park, where they will meet with members of the Facebook engineering team:

• The Paperclip.io team, from Taipei. Paperclip.io indexes and sorts the things you've liked on Facebook and across the web, so you can easily browse your likes by category or by the date you liked them.

• The Chained Story team, from Buenos Aires. Chained Story is a web version of a storytelling game in which players take turns adding a sentence or paragraph to a story. The completed story can be published to a user's timeline.

• The BoostMate team, from Moscow. BoostMate analyzes your social graph and the connections you have with all your friends, producing a ranking of who you're closest to, who you interact with least, and whether those interactions were positive.
