LifeNaut is a service that allows you to create an interactive avatar, upload content, and even an DNA sample so that you can “create a free back-up of [your] mind and genetic code.”
As you enrich your profile, your avatar becomes more “intelligent” and can answer questions about you more fully and correctly. Your content can tell the story of your life. Lastly, your DNA sample is frozen and stored for eternity.
This is part of a new class of online memorials that includes Virtual Eternity.
