Brickit is a new iOS application that will breathe new life into your old Lego collection. Simply pour your Lego bricks into a pile, and the app will analyze them to determine what kind of Lego bricks you have, what new inventions you can make with them, and how to assemble them. It will also offer you full assembly instructions, and it can also assist you in locating certain pieces inside a pile of items.
