I and others created a wallet that lets you use locations about the size of a city block using deterministic geohashes. Humans remember places WAY easier. Grateful we won awards at B25. VERY experimental I might dust this off and make it actually secure by picking a few thousand world landmarks and making those your memory palace instead of locations that could be guessed by the panopticon. I tried to make it cypherpunk aesthetic meets Rebel Gold (free mason themed lol)
