Yahoo Time Capsule is the world’s largest time capsule — commissioned by Yahoo and designed to take a fingerprint of human culture in 2006.

Structured around ten universal themes (Love, Sorrow, Anger, Faith, Beauty, Fun, Past, Hope, Now and You) each bearing an open-ended question (What do you love? What makes you sad? What makes you angry? What do you believe in? What’s beautiful, What’s fun? What do you remember? What is your wish? Describe your world. Who are you?), people could respond in one of five simple ways – with words, pictures, videos, sounds, and drawings.

Translated into ten languages, Yahoo Time Capsule was open online for 30 days, accepting the world’s contributions. The project was punctuated by a three-day event outside Albuquerque, New Mexico, where the contents of the Capsule were projected onto the ancient red rock canyon walls of the Jemez Pueblo for three consecutive nights, from dusk until midnight. The contents of the Capsule are now housed at the Smithsonian Archives in Washington, D.C..
