summary

Memory Palace encodes secrets as first‑person paths through a procedurally generated 3D labyrinth implemented on Android with OpenGL, using a 21×21 grid split by a genetic algorithm into Tetris‑shaped rooms with distinctive textures and doors; a 20‑participant study shows complexity‑controlled paths yield 70% remembered vs 30% after one week, are far harder to shoulder surf (5% shoulder‑surfed vs 65%), and cost about four extra seconds to enter on average.
