My Wii Guitar Idea
I still don't have a Wii (out of stock everywhere and also I haven't tried very hard) but that hasn't stopped me from fantasizing about things to do with the accelerometer in the Wii controller.
First I came across this collection of videos of the 20 Greatest Guitar Solos. My main thought was "a little guitar solo goes a long way".
Then I watched this Wii Wiimote Ableton Live Controller video.
So here's my Wii guitar idea:
1. Strap the Wiimote to the headstock of your guitar.
2. Run your guitar through some effects, such as say, a flanger or a filter.
3. Have the Wiimote control various expressive parameters of the effects.
This way, when you pull this move:
Not only would you be looking dead sexy, you'd also be making expressive changes in your guitar sound based on the movement of the accelerometer in the Wiimote. Everybody wins!
