Boinx MiracleSight is the latest toy for Apple’s iSight video camera (and works with other Webcams, too). The “magical mirror” screensaver watches what happens in front of your Mac and reacts to motion by drawing bubbles, playing a sound file (such as a GarageBand loop) or speaking a text phrase using Mac OS X speech synthesis. It can be downloaded at the Boinx Software Web site. It’s free; however, the company does accept donations, which will be used on future versions of MiracleSight.
