- mycelium 11y agoHow do you increment the count as you count? Memorization? I can count binary. I don't know which bit/finger to flip to count in gray code.
- osense 11y agoJust as there is a pattern to "regular" binary coding, there is a pattern to the Gray code -- albeit, perhaps, a more complex one. I'd imagine that after practicing counting from 0 to, say, 15, you'll be able to count further up on your own.

- nicklaf 11y agoI just tried this, and I'll say that it's not too easy. My middle finger doesn't really want to go down when the fingers next to it are still up.
