This past summer, some of the most passionate and creative web developers out there innovated with the File API in our July Dev Derby contest. After sorting through the entries, an all-star cast of former judges–Peter Lubbers, Eric Shepherd, and David Walsh–decided on three winners and two runners-up.

Not a contestant? There are other reasons to be excited. Most importantly, all of these demos are completely open-source, making them wonderful lessons in the exciting things you can do with the File API today.

The Results
