I teamed up with Bjarne Fisker Jensen as programmer and made 'God Hood'.
The 'game' was an experiment to use tracking markers for phones and tablets and is loosely based on this Peter Molyneux 'Robin Hood' quote.
You point device's camera at the marker that will then track and display the 3d game environment on top of the marker. Tap and hold screen to draw bow, release to release at the little guards. that's it. Our game mechanics ideas was never fully implemented but we got to try a very cool intuitive way of interacting with a 3d environment.
