Interesting, but the fact that a sequence of finger positions indicates a number sounds risky in a blink and you get the wrong result kind of way. When we travelled to China years ago we were advised to learn the one-handed 1-10 gestures[1] which we were assured was in common use there, and solves one of the basic problems of asking for specific quantities of things without language. I guess that if you had an agreed endian (LSH / MSH?) you could represent all integers from 0-110 in a single two-handed gesture. Obviously, with 10 fingers, you could also represent 0-1023 by holding up various digits - and that's needing only two states per finger. How quickly or easily others would be able to read that representation is a different question. Plus most of us would need some training exercises to recover finger independence of pinky and ring.
