On the increasingly small off chance your computer doesn’t have it’s own webcam (or you’ve blowtorched it because those aliens from Tau Ceti II were spying on you), German developer Drahtwerk has a clever solution: an app that lets you turn your iPhone into a wifi-tethered webcam.
iWebcamera ($5) includes a pause-mode, two quality options and a “send drivers by e-mail feature,” which is apparently some BS that Windows users need to deal with.
