iBetelgeuse (pronounced: iBeetlejuice) is a free and open augmented reality browser that adds a whole new dimension to your reality. Such a higher dimension can contain all kinds of text and graphics that can be displayed on top of the camera image as you move and look around with your iPhone. A dimension can also be interactive, allowing it to be anything from a simple informational layer to an interactive social game. In addition, iBetelgeuse has a built-in QR-code scanner, making the possibilities endless.
Due to the open nature of iBetelgeuse (even the source code of the app can be found online) you can potentially find dimensions all over the web. They can be made by you and others without restriction using simple tools and published and then used by people all over the world.
One place where you can make simple dimensions is the Betelgeuse Designer:

To learn how to make more advanced dimensions visit the iBetelgeuse page on GitHub: http://finalist.github.com/iBetelgeuse/
Note: iBetelgeuse needs an internet connection, location services, a compass and an accelerometer to work. For the full experience, GPS-accuracy and a camera are a must. Therefore the application will work best on iPhone 3GS and iPhone 4, but also, in a degraded fashion, on iPad.
