This project's own source code, pinned to the walls of a small house. Each wall panel is one page. Keep turning the same way and the panels behind you re-page to the continuation, so a room holds far more than one turn's worth of code — but the ribbon stops at the first and last page, so you never turn into a wall of blanks. Each file has its own colour, and the floor tells you where it starts and which way it runs.
