Yahoo is going to create a time capsule to be buried in Silicon Valley as well as beamed from Mexico into the cosmos.
The internet giant invited people worldwide to contribute pictures, videos, songs, ideas, drawings or anything else they could digitise for a "first-ever electronic anthropology project'' to document human life in 2006.
Submissions could be uploaded via the internet to regionalised Yahoo Time Capsule' websites.
Suggested topics included love, anger, fun, sorrow, faith, beauty, hope, and "you".
Yahoo will celebrate the project with a grand three-day ceremony at The Pyramid of the Sun in Teotihuacan, about 40km from Mexico City, beginning October 25.
The time capsule will be opened when Yahoo celebrates its 25th anniversary in 2020. More details over here.
