"Of all the Arduino projects we've seen 'round here, this is certainly one of them! Using nothing but a Graphics LCD, an Arduino, and a WebSocket server he wrote using Python / Tornado, this young engineer created a system that allows him to connect to the server with his iPod touch (or any browser, we suppose -- although he's apparently only tested this with Chrome on his desktop PC) and draw a design on the web browser. In turn, his movements are recreated on the LCD. Pretty mean feat, if you ask us. If you'd like to marvel at his code -- or even try it out for yourself -- hit up the source link. If not, be sure to at least check out the thing in action. Video after the break."^^<http://www.w3.org/2001/XMLSchema#string>
