The rather excellent video below is a wall-painted animation: essentially a stop-motion animation created by painting a sequence of still images on a wall and photographing them, then running the photos together into a film.
It was created by the street artist Blu, who describes it as the result of "months of work and hundreds [of] buckets of paint". That's hardly surprising, given that it tries to illustrate the history of the universe since the big bang, with a particular focus on the evolution of life on Earth.
It's very impressive indeed, so without further ado:

That guy painted all over some town somewhere. Great work, but that must have taken forever!
