GlovePIE 0.43 - nice tool for wii gesture recognition

GlovePIE is a free Programmable Input Emulator, originally for the Essential Reality P5 Virtual Reality Glove, which now supports a huge range of input devices, especially the Nintendo Wii Remote (Wiimote).

GlovePIE is used to map gestures, button presses, and other actions to keyboard keys, mouse input, or joystick buttons and axes.

Version 0.42 includes lots of hardcoded Wiimote, Nunchuk, SIXAXIS, and Dual Shock 3 (PS3 controller) gestures. So now it's as easy as:
Ctrl = Wiimote.Stabbing
Space = Wiimote.CircleClockwise
