This is an intriguing site. While digging the tunnels for the Amsterdam subway, Archaeologists categorized some 20,000+ objects going back 12, 000 years.

You scroll endlessly through them, click on an object to learn more about it, where it was found, what it was used for.
Probably the best new website I've discovered this year.
