update: regrettably, I was asked to remove the two separate Duelity movies from YouTube. instead I have now added the parallel version, which only was added to YouTube by the original source after this post.
a compelling split-screen infographic animation that tells both sides (in reversed visual styles) of the story of Earth's origins in a provocative journey through human history & language.
while also enjoyable separately, the trick is to see both movies in parallel,
either below each other (try to start both youtube movies simultaneously) either by starting the movie below, or side-by-side on the duelity website.
