Hacking home screen

[Joe]

I'm trying to hack the home screen so my application exists as a top
level choice (along with "Applications", "DevTools", "Contacts",
"Browser", etc).

Using the documented intent filters doesn't do the trick

<action android:value="android.intent.action.MAIN" />
<category android:value="android.intent.category.HOME"/
>
<category
android:value="android.intent.category.LAUNCHER" />

Any clues? I saw a youtube video where someone demo'd a custom app on
the top level - so I know there is a way.
