Wow - this is amazing! And especially with this speed of ~0.25 seconds 
for finding a face! How are you accessing OpenCV - via SWIG or CTypes?

I'd suggest to create [[OpenCV]] and start linking to infos, howto's and 
examples. That will make life much easier for all who want to play 
around with image recognition on the xo in the future.
