MotionX has released a free app called MotionX Dice [App Store]. The free dice application provides you with five dice that can be rolled by simply shaking your iPhone. The physics and visualizations serve as the basis for their $4.99 game MotionX Poker [App Store].
The $4.99 Poker game uses the same dice-rolling technology. By also adding betting structure and the ability to unlock higher tables and dice, MotionX has done an excellent job in creating an enjoyable gaming experience.REVIEW FOUND HERE
