Dunno, I suspect that most folks wouldn't after a weekend remember more than "It was mostly purple". Seems like you need something like a small cartoon with variables like: 1-8 characters, 16 skies (moon, sun, storm, windy, snowing, hail, etc), 32 scenes (playground, beach, office, home, yard, forest, ski slope ...), species of each character, emotional state, etc. Then people would remember things like 4 characters, it was snowing, and a mad cat was talking to a sad dog and 2 kids dancing on a mountain top.

Will people really tell the difference between on a snowing beach with a sad princess and a neutral expression genie, versus on a snowing beach with a sad princess and a happy expression genie? Because: (EDIT: Unfortunately, HN seems to strip emojis). 1..n..8 characters, assuming 1000 emojis, is somewhere ~along 1000^9 bits of emoji. 16 skies is 16 bits of entropy. 32 scenes is 32 bits of entropy. You multiply those together, and you get 5.12e29, or 2^98. That is considerably smaller than 2^256. ----- To get to 2^256 bits of entropy with an emoji set, you need 25 emojis. That's very long. That's like (HN stripped emojis). Can you tell a difference between that and ? At a glance?

  Indeed, trick is normal humans are not going to remember, let along recognize 256 bits of state from a picture. Seems like the best you can hope for is enough bits in a fingerprint that users can tell when it changes and make it harder to find a fingerprint that fools the user.

Blockies (sha-256 avatars) worked for me as a quick sanity check to make sure I'm sending to/from the correct wallet. You're dead on, I would remember them as "mostly purple." Never had an issue. I usually check the last few digits as well just to make sure.
