Yes, depending on what audio inputs and video outputs you have on that 
iBook. You'll have to adapt your outputs from your sound board to the 
audio inputs on the Mac and check to make sure the video inputs on the 
LCD projector match the outputs on your Mac.

On an iMac:  board 2x 1/4" > 1/8" mini stereo jack gets the sound in to 
the Mac. VGA to VGA for the video to the LCD. eMacs use a mini VGA to 
VGA adaptor. Titanium G4's use a DVI to VGA or s-video etc. You might 
have to build a custom cable or two, but it's doable.

  G-Force has a standalone Visualizer that will do the visuals. G-Force 
isn't Altivec enabled so clock speed and video cards affect performance 
more than G3 vs. G4.

I've been doing this with an NEC projector (don't have the model, it's 
at school) and it ROCKS!
