Does this hacker ever sleep? The prolific Jeri Ellsworth is at it again. Here, she builds a 52″ Etch a Sketch with the screen from a rear-projection TV, some tent poles, screen door pulleys, some cheap Harbor Freight drill motors, a golf tee (for the stylus), and some aluminum powder. They also designed a web interface for their USTREAM live chatroom and are working on hooking up the device so that people in chat can operate the Etch a Sketch. Let me guess how many naughty grade-school squiggles and “bad words” are going to show up on that screen?
