Finger Binary

What's Finger Binary?

Here is a description of Finger Binary in Wikipedia.

Finger binary is a system for counting and displaying binary numbers on the fingers and thumbs of one or more hands. It is possible to count from 0 to 31(2^5−1) using the fingers of a single hand, or from 0 through 1023(2^10−1) if both hands are used.

How to work?
