While some may think laser pointers aren't good for anything other than hijinks that may or may not cause blindness, intrepid hacker "mnt" apparently has a greater affection for the technology that's been the cause of so much embarrassment. Using nothing more than a cheap webcam and some mad coding skills, he's manged to turn that run-of-the-mill laser point into a gesture-based interface device, employing Grafitti-like symbols to control media playback on his PC (check it out in action after the break). Sadly, he hasn't made the necessary software available to the public just yet, so unless you've got the skills to whip up your own, it looks like you'll be stuck with your antiquated remote control for a while yet.
