Here are a few audio libraries for the processing platform :

Today I got two different things to happen with the eyebrow switch. I'm still using the same arduino sketch as last time with the different shades of grey. I don't see myself changing this unless I change the input device.
SimpleRead_eyebrow_RGB:
This sketch allows for the eyebrow switch to change a color displayed onscreen.
none: 0, 0, 0 (black)
left: 255, 0, 0 (red)
middle: 0, 255, 0 (blue)
right: 0, 0, 255 (green)
left + middle: 255, 255, 0 ()
left + right: 255, 0, 255 ()
middle + right 0, 255, 255 ()
all: 255, 255, 255 (white)

SimpleRead_eyebrow_circle_move:
Moves four circles in a mirrored pattern based on eyebrow movements.
none: stationary, no action
left: move circle (top left one) left
middle: move circle up
right: move circle right
left + middle: make circle smaller
left + right: move circle down
middle + right make circle larger
all: move circle up (to be changed to something more interesting.)
