Armchair archaeology: find lost civilisations using your laptop

Ever fancied making like Indiana Jones and searching for ancient treasures? Now you can do it in your pyjamas

Indiana Jones had to eat chilled monkey brains, escape from snake pits and punch Nazis. I'm at home in my pyjamas, looking at blurry bits of ground and using 90 seconds of training to click "yes" or "no" to the question: "Do you see evidence of looting pits in the white highlighted area?"

This is archaeology in the digital (and, er, real, and very amateur) age. A new project invites armchair Indianas everywhere to survey isolated tiles of satellite imagery, marking them as potential sites of interest or, in my case today, crime scenes.
