I don't (think I) know Andy Latham, but I think I'd like the guy. Apparently he heard Patrick Copeland's QCon's talk on pretotyping and to prepare for something called Capital Libraries Hack Day, he decided to create some paper iPads – presumably for pretotyping iPad apps.
Nice going Andy. I hope the iPretoPads help you come up with some good candidates for the right 'it'. We'd love to hear back from you after the Capital Libraries Hack Day.
