If you've ever been to a big event that embraces social media you may have seen a "Twitter Wall" of some sort. These are popular at all of the BlackBerry events we attend and essentially broadcast specific Tweets to a large screen for everyone in attendence to see. TweetWall gets the job done on your BlackBerry PlayBook pulling from Twitter with the hashtag of your choice. You can hook up your PlayBook to a larger screen via HDMI and broadcast Tweets all day long. TweetWall is currently in beta but it looks very promising. Check out the video above for a quick demo, then hit the link below to get in on the beta.
