If you visit http://search.twitter.com, you will see that they have a search page that auto updates when new tweets have been posted with certain keywords. I can’t watch the site all day, so I decided to write a little tool that will flash the messages on my screen using Growl. Here’s how I did it.

We’re almost done! The remaining screencasts are already recorded, but not edited yet. To speed things up, I split it up into 3 or 4 screencasts. This one shows how to make the site look and feel like Twitter and also populates the right side column content. A bit of CSS, lots of Rails, and more of my ramblings 😀
