No new features: just rebuilt and repackaged to run on AIR beta 3. Note that the newest AIR beta properly displays animated GIFs, which makes this silly app look much better :)
I did have to make a change from the original version, to conform to the new AIR HTML security model. My original code used setInterval, with a string to execute as the first parameter. This is a no-no in the new security model (since the executable string is the equivalent of an eval). I could have put the whole thing into an iframe in a non-application sandbox, but instead I used the AIR-native Timer class, which did the trick.
