Subject: Hand as abacus

I saw some kids using their hand as an abacus in the television. They used 
the knuckles and valleys between the knuckles on one hand and counted on them 
with the fingers of the other hand. They were able to do various calculations 
with great speed and accuracy and were thrilled by it. I have looked 
everywhere to try and find this method. I believe it is a part of the 
folklore of our nation that has almost disappeared. Have you ever heard of 
learnign about mathematics this way? Do you know where I can learn this 
method so that I could teach my students?
