Or you could use them for
Winamp Visualization!
Stefan Slonevskiy has created a visualization plugin for
everyone's favorite corporate sellout
It makes your
keyboard lights act like an analyzer, adjustable
sensitivity and
everything!
Granted, it's a ridiculously random trinket, but I like trinkets
He has also created a
C++ lib for those who want to include keyboard light
tomfoolery in their apps
all this and more can be acquired at his website:
