Do you fear that you're going to miss out on the latest news when nature calls? Sure you could always use your phone or tablet to stay in touch while you're sitting on the throne, but that's kind of icky. Mario Lukas figured there had to be a better way, so he built this toilet paper dispenser that prints his Twitter feed right onto the roll.
Built using parts scavenged from an old CD drive and an Arduino controller, Mario's roll holder connects to his home network to access his Twitter and RSS feeds. I assume he has some way to turn the printer on and off from his computer, otherwise he could be faced with a mountain of paper following a long bathroom break free stretch.
I really don't want to know how he responds to incoming tweets while he's in the bathroom.
