I installed Itching thumb (was itching to di it after seeing the first post) on my HTC EVO. While it does look good, I see that my version is quite different than the video one. Only 3 screens to add stuff, hence no place for widgets and then the webs like cards carousel look is great - but hi quality pics only supported on rooted device (mine is not). Overall nice, but not too functional for me. Again, maybe I am using an older version.

But these do show how different types of launchers are there for Android. Am liking it so far, even though there are some sticking points as well.
