We have applied this technology to a dice app because it is a concept that everyone can understand and play with:

In short: Movements of the device (an Android phone) are tracked with sensor fusion, and applied to a box that is visualized on the screen. A few dice move freely inside the box, handled by Bullet physics. Glass cover prevents them from bouncing out of the box.


We are giving it away for FREE (and without advertisements), so if you have an Android device, download it from Google Play:

Have fun with it! This is our first app with Bullet physics, so we're looking for your feedback.
