Build a 3D castle that works as my second brain. The notes are in [folder path]: memories, experiences, knowledge, books I've read and movies I've watched. Give it different rooms, a wall of memories, a movie room and a bookshelf where I can click any book to read my notes on it.
Visual breakdown
The creator kept about 400 files of memories, knowledge, books and movies by chatting with Claude a little each day. He then gave Claude Code a prompt and the path to those notes, and it built a 3D castle with a room for each part of his second brain.
The problem: A big pile of personal notes is hard to browse. He wanted a more engaging way to walk through his memories and knowledge.
