The details of Tom's hardware hack at PaperCamp: an old-school printer receipt printer hooked up via arduino.
Chris Heathcote's notes from his PaperCamp talk on guidebooks.
I had a good browse through "Things Our Friends Have Written On The Internet 2008" at PaperCamp. It's lovely.
Matt has organised PaperCamp for this weekend and I'll be heading along. Should be good fun.
