The website of "the caves of Lascaux" which I found through the blog of Mr. Marc Vermeersch(http://marcvermeersch.wordpress.com) can be opened by clicking the underneath screenshot.
It's really fascinating for someone who is interested about history of humans and the history of images.
A more detailed article by Mr. Vermeersch about humans making images thousands of years ago can be found here. The original blog is in Dutch, but Google translation is an option.
