Threaded v4l2 app combined with ruby will look at you through webcam and when I finish it, it will do sound like wind chimes, but instead of wind -- you'll be the cause and instead of chimes, there'll be your speakers.

Uses V4L2, pthreads, ruby. Needs that linux thing on x86. Can be ported. Written in C and ruby. Should be pretty straightforward to compile, if you're on the same env.

Created for the amusement of self and getting more familiar with MRI's internals.
