The last time we saw Ben Wu, he was busy hammering away at Quantum Phantom -- a prototype program that allows users to manipulate their desktops with a simple webcam. Now, the engineer has expanded the concept to smartphones, as well, with a system that effectively turns any camera-equipped handset into a wireless mouse. To achieve this, Wu hooked up his Android phone to his PC via WiFi and used the IP Webcam app to create a video stream server. The results, by Wu's own admission, aren't exactly elegant (due to an unwieldy configuration process and low-res camera), though he still managed to use his creation to sketch an onscreen smiley face. Watch it for yourself in the demo video, after the break.
