BTStack is the name of a new project that allows the Wii controller to communicate with the iPhone using Bluetooth.

The video it shows the 3D representation (using the Open GL | ES) controller, which manages to take all the positions of true remote control, via Bluetooth. Currently, the агтсешщтфдшен is minimal but future implementations could be very practical, especially with the iPhone 3GS, which thanks to the compass, could be used just like a real Wii remote.
