From the developer:
Watercooler is a lightweight video conferencing application that requires low memory and CPU usage. The utility is very easy to use. It has only two buttons, which makes it intuitive and straightforward. You don’t need to sign up for anything with Watercooler. When you download the app, you get your very own anonymous Watercode, which you can send to anyone you want to talk to.
