iTwist for iSight
iTwist, a program for use with an iSight camera, is now available. iTwist allows users to answer and hang up iChat video phone calls without the use of a keyboard or mouse. iTwist will interrupt the screensaver to show who is calling, and allows the user to answer or hang up the call by twisting the iSight lens open or closed. iTwist also allows users to switch off any specific function directly from iChat AV preferences. iTwist automatically changes the screen view mode to fullscreen for all iChat AV video calls, and all incoming video, audio, and IM panels are shown directly onscreen. iTwist requires OS X Tiger, iChat AV and an iSight camera for use of the video phone options, and costs $20.
