ooVoo: Free Multiple Video Chat Client
ooVoo is an elegant and powerful video conferencing and IM client that combines elegance with functionality. Unlike some video conferencing applications, ooVoo is very easy to get running with your webcam and it can handle very high-quality cameras - up to 2 megapixels, depending on the speed of your connection. With ooVoo, you can talk face-to-face with up to six people, add an ooVoo link to your blog or online profiles, send and receive video messages, and it's completely free.
What's really nice about ooVoo is the ability to place your contacts, and their video images, down the side of your screen in a sidebar simultaneously. This way, you can chat away to all of them at the same time and see them at once. ooVoo also allows you to add video effects such as sepia, blurring, and morphing during chats and video calls, setting it apart from other popular VoIP apps like Skype.
Unfortunately, ooVoo automatically adds itself to your startup items without prompting, which can be inconvenient for some users. However, overall, ooVoo offers an excellent video chat experience with a very good-looking interface and feel.
