Here are some video trivia game widgets from PopJax.com. The widgets are pretty straight forward and interesting enough to pass the time. They are leveraging YouTube videos and YouTube services for their widgets. This is a smart move as that will significantly lower their overhead.
The widgets have login and registration within the widgets, this is a nice touch. No need to force people back to home base if it’s not needed. Though, there is a Community/Social Network going on.
