Tweetwall makes it easy to display Twitter at your event. You just load the application, search for your event, and then select it - the app will take over from there. The program provides you with full-screen mode without having to remember the keyboard key combination. Your cursor will automatically hide after a few seconds (until you move it) so that your attendees don't have to see it. Your computer won't go to sleep while your Tweetwall is being displayed.
