This a site about finger binary among others :3
Finger binary is the art of counting in binary of your fingers.
Using this method you can count to not 10, not 100 but 1023‽ This opens a lot of possibilities! One of which is easy arithmetic up till about 1000, a physical way to remember numbers, as well as a physical way to experience those abstract calculation and a more intuitive to understand and use binary and binary arithmetic
