Why not pass some time reading ancient papyrus? Ancientlives.org is the home of a crowd sourced scientific project where participants are asked to help translate fragments of papyri that belong to the Egypt Exploration Society. This is another Zooniverse project. They’ve got quite a lot of projects running in various fields, so if you want a great excuse to sit in front of the computer, this is probably a good site to bookmark. Like all the zooniverse projects, the interface is intuitive & well designed, but it still feels like you’re contributing to a serious scientific project – which of course, you are.
