Sightspeed looks and feels different from just about any other video chat application, the interface is unlike your typical text I.M. application, like Skype or iChat.

Instead SightSpeed is sort of a "video desktop"--it has a wide rectangular window instead of the typical buddy list interface you may be accustomed to if you use Skype. At first, I couldn't understand why the Sightspeed designers chose this tack, but now it makes sense. Sightspeed is probably the friendliest video chat program around. Sound and video quality are on par with iChat. Some other unique features include video mail and pan-tilt-zoom controls, so you can actually control the camera of your chat partner.

Sightspeed runs on Windows and Mac, so iChat users who've been frustrated by the lack of Windows compatibility for video calls will definitely want to check it out.
