OvrStream can pull data from Twitter by directly connecting to your Twitter Account.
First, assign a Twitter behavior to one of the graphics in the scene that you want to automate.
This will open up the Twitter log in window. Sign in with your Twitter account to receive notification data.
After you sign in, all graphics set to Twitter input behaviors will automatically play when data is received from Twitter. You can disable automation by unchecking the box on the left of a graphic to disable automatic playback. You can still manually play the graphic if you want.
You can automate Twitter Follower Alerts.
