The Century Letter
Every citizen writes one letter to the city of 2126.

The Vision
A civic ritual, not an app: once in your life, you write a sealed letter to the residents of your city one hundred years out, and the city archives it in a public wall of brass vaults. The reading, a century later, is a municipal holiday. The point is not the letters - it is what writing one does to the author's sense of time.
Main Features
- 01ONE SEALED LETTER PER CITIZEN, ONCE IN A LIFETIME
- 02PUBLIC WALL OF BRASS VAULTS IN THE CIVIC ARCHIVE
- 03OPENING CEREMONY FIXED BY STATUTE, A CENTURY OUT
- 04SCHOOL PROGRAM: READING THE PREVIOUS CENTURY'S LETTERS
The Long Story
We have no institutions that ask an ordinary person to think past their own life. Wills face backward; pensions face thirty years. The Century Letter is a machine for manufacturing long-mindedness, one citizen at a time.
The design constraints are all about trust across time: acid-free paper, brass vaults, a public ledger of deposits, and an opening ceremony scheduled by law, so no future council can quietly cancel the past's appointment with the future.
