Mobile developer Fingerfunk has created a line of very cool T-shirts with a Giger-esque design that comes to life through Augmented Reality. You can see a demonstration of the T-shirt in action in the video below.
The tracking image and T-shirt can be acquired at the developers website here. The Android app can be downloaded for free here. An iOS version has been submitted and is waiting for approval. More information on the design and plenty of behind-the-scenes images can be found here.
Update 29/08/12: The iOS version is now available here.
