If this thread is still available for all to see (I couldn't find it, it's so buried) Here's something I thought the OP and others might benefit from. It comes from a UK Forum I frequent.
Free 2 Person Code System
by phillipnorthfield » Thu Oct 18, 2012 6:45 pm
For anyone interested, and because there's very few occasions when I'd be able to use it myself, I am writing down my 2 person code method, that as far as I know is original. Although if anyone knows otherwise, please let me know, I'd be very interested.
This system allows you to signal in one gesture one of 60 different items. (Yes 60!) That means you can send an entire playing card in one go.
It looks relatively natural, and is fairly easy to learn once you understand the concept behind it.
Ready? It uses fingers..... OK, I'll expand. The number system we use in our day to day lives is called base 10. However, before the Romans invented this system with the 10 basic numerals, the Babylonians used something called base 60.(Apologies for the history lesson, but it's all relevant) For those interested, that's why there are 60 seconds in a minute and 60 minutes in an hour.
Now imagine you wanted to send the number 7 to someone and you could only use your fingers. You'd put up 7 fingers, obviously. What if it was 14? A ten and a four. But that's two 'moves' . Now imagine 24, 34, 44, and even 54. That's up to 6 moves to send just 1 number.
Fortunately, that's where base 60 comes in. Imagine that each phalanges (section of your finger) of your left hand,represents 5, and putting your thumb on that part signals whatever total is there i.e : Imagine my thumb is at the base of my index finger, this would represent 5, the one above it, 10, above that 15, the first phalange on the next finger 20, and so on. All the way until we reach the final phalange, the tip of the little finger which represents 60. The number of outstretched fingers (thumb doesn't count) on your right hand is added to this to provide any of the numbers from 1 to 64.
By simple pretending to scratch and rub your finger with your thumb, the number can be coded in a matter of seconds. This can then correspond to anything you require, which I'll leave to your imagination.
Apologies if it is a little complicated to follow my instructions, the method really isn't too hard, and I hope someone gets some use or ideas from it.
