A Simple Twitter Tool for Events

TweetBubbles is an Adobe AIR application that enables event organizers to show relevant tweets on big screens or presentations based on a keyword.

First decide what will be your event's #hashtag and make sure to inform your participants about it. Then, install the application, enter your chosen keyword (your event #hashtag), and let it stream through a presentation, or any wide screen at the event. Additionally, you can choose the position of the balloon (both sides, left, right), and the balloon transparency.
Tweets will appear as long as people uses the right keyword.

There are some web clients that offer you the same and you can also use Tweetdack to perform this action, but the difference is that TweetBubbles has a nicer layout and it can actually appear on top of a presentation because of it's transparency.

There are some missing features that would make it a better tool, such as speed control, color selector, and a languages filter, but overall it's a very useful client.
