I think it would be interesting if someone came up with a visual hashing
algorithm, where small changes in the inputs had uniformly random visual
outputs. I was testing jdenticon with my node id:
03f3c108ccd536b8526841f0a5c58212bb9e6584a1eb493080e7c1cc34f82dad71
I was surprised to see that small changes to the first digit didn't
change the visual output at all. Whether or not this is a useful
property in this use case, it's something to keep in mind.
Cheers,
Will
