1-to-1 tracking with Arduino and a Wii Nunchuck

I posted this video on Facebook a little over a year ago in July of 2008, accompanied by a note that I'd be reshooting it on account of the shoddy quality. Funny thing is, in retrospect it's the best I've shot yet. There'll be a new one coming soon to show off the new boards (waiting on FedEx to make good on a lost or stolen parts shipment) and the simple new features I've been coding into the Processing sketch, and maybe even the robotic arm working as a waldo. And yeah, I'm still working in Processing. Haven't managed to stick it out with any of the more robust frameworks I've tried.
