If you have a Google+ account, you can create a hangout where one or more of your friends can join you for a video chat. The whole thing is easy to set up and use (but a bit difficult to find, at first).
Start by going to your Google+ page. In the Hangouts area on the right, click Start A Hangout. Specify whether you want to invite everyone in your circles or just selected people and then click Hang Out.
