A modern nerd legend for you this week, as we chat to John Graham-Cumming about his new project, Plan 28, which aims to "finish Babbage's work" by raising the cash to build an Analytical Engine from original plans. John has previously successfully petitioned the Government to formally apologise for the treatment of Alan Turing, and is the author of the Geek Atlas. All that, plus potato printing with Kinect, space balloons, Star Wars and yet more Mexican snackfood in this unnecessarily spicy serving of your favourite podcast.
