MidiWii is a small program written in Java that translates the messages sent by a WiiMote into MIDI messages.
I have released the source code in my repository and also a downloadable executable jar here.
Things you can do with MidiWii:
– control some of your Resolume commands with the wii mote
– play some notes with the wii mote
– control some effects on audio and/or video by moving the wii mote
And here a couple of screenshots:
