Since Apple dropped the non-disclosure agreement (NDA) from the iPhone SDK, iPhone developers everywhere have started some awesome projects. From writing a book, to providing examples like Apps Amuck is doing, the development spectrum has exploded. The idea behind of Apps Amuck is to build on the iPhone app tutorials that Apple provides for developers. They are currently giving away one app per day for the next 31 days.
The tutorials they provide are small, one trick ponies that allow you to perform tasks like finding your location, building a fire, figuring out your IP address, and more. The site allows you to see a screenshot of the application, read a description, and download the source code to play around with. If you have a developer provisioning file (meaning you've been accepted into the developer program), you can even sync the applications over to your iPhone or iPod touch.
If you are not an iPhone developer and wish to play around with the applications, you will soon be able to download them from the iTunes App Store. For more information about the project, visit the Apps Amuck website.
Thanks for tip, Chris!
