Hmmm.... I'm not sure if the 1st posts article is the one I saw on Tv.
There's a pretty big paiting in a cave, I forgot where. The cave isn't fully a cave, it allows light in (sometimes)
At a certain season of the year, while the sun's setting, light come into the cave. And it depicts the story of the painting, in different changing colors.
Archeologists claim it was the 1st depiction of a movie ever made. Something like that.
I think it was 12 000 years old.
