The Long Now Foundation is currently building a clock that is meant to last for ten thousand years, aptly named the Ten Thousand Year Clock. Prototype 1 was built in the year 01999 and rang out two millenial bongs in celebration of the year 02000.
Their other projects include the Rosetta Project, which aims to archive every known human language and has currently amassed the largest database of human language data in history.
