Hexagon:
Using only the universal and powerful Macromedia Flash plug in, running in a browser window, you can keep in touch with your colleagues wherever you are in the world. Not only can you see their present 'state-of-being', or get an immediate response to a 'quick' question using the inbuilt text chat, as with many other types of software, but you can actually see them working at their desk. As if they are just next door!Or not working. Ha!
